I have a COM+ application installed on my machine which has two components. This COM+ application was created using an SetupCom.exe file which was made using C# code some years bac. It used to install and create a COM+ msi file, but now I don't have access to that code, and I need to remove one component from this COM+ application - which is no longer in use.
So, I searched using google and I found some PowerShell scripts that remove the components from the COM+ application, but they don't create the msi file. I need this updated COM+ application msi\installer file so that I can install it on multiple machines.
Below is the Script which removes the component from COM+ application, but doesn't create an updated msi file.
$comCatalog = New-Object -ComObject COMAdmin.COMAdminCatalog
$appColl = $comCatalog.GetCollection("Applications")
$appColl.Populate()
$app = $appColl | where {$_.Name -eq "COMAPPNAME"}
$compColl = $appColl.GetCollection("Components", $app.Key)
$compColl.Populate()
$index = 0
foreach($component in $compColl) {
if ($component.Name -eq "SOMECOMPONENT.NAME") {
$compColl.Remove($index)
$compColl.SaveChanges()
}
$index++
}
Writing the below, I remembered having written something similar before. Here it is: Would this method of installing COM+ work?
There is support in all major deployment tools (thee main bullet point links) to do COM+ deployment. WiX may provide the most flexible features for COM+ installation, but I have never used them.
COM+ deployment has always been a bit strange to deal with. Despite all my years doing deployment I have only done it a few times. And several times I have had a lot of problems with it. I even had a guy make a basic "hello world" COM+ application that I sent to a deployment vendor to illustrate how they did not do COM+ properly. No luck.
Typically I have ended up exporting a COM+ installer MSI from the Component Services (Launch suggestion: Windows Key + tap R type comexp.msc and press Enter). After setting up an application as you want it running, you right click it in the list and export an MSI file (in your case I guess it should already be set up):
This exported MSI file is not - shall we say - the greatest thing since sliced bread. If you want to modify it, it will quickly break in some fashion. There is an undocumented APL file in there with COM+ settings that I never understood how to handle on my own. Just use the MSI as it is - if you can.
Some Links: I took it a bit far with these links, just go for the bolded ones.

I am developing desktop database application. Using rdlc report and reportviewer. Everything was fine in developing process, reportviewer was showing all data smoothly. I deploy app with Inno Setup. But when I install the app, the reportviewer is not showing data. While data is correctly inserted in the tables.
For applications that work incorrectly or fail completely, when installed by Inno Setup to Program Files folder, the first thing to test, is to try to deploy the application manually to the same folder.
If the application fails even after a manual deployment, the most usual problem is that the application requires a user to have write permissions to application folder. As on modern versions of Windows a user typically does not have write permissions to the Program Files folder, the application does not work. So the problem usually has nothing to do with Inno Setup, but it's a problem of the application itself.
To solve the problem:
The best solution is to redesign the application so that it does not require write permissions to its folder. Windows applications should not require write permissions to their folder. That's against Windows guidelines. The application should write data to a user profile folder (C:\Users\username\AppData) or to a common data folder (C:\ProgramData).
A dirty workaround is have the installer grant a user(s) write permissions to the installation folder. Do that only, if you cannot get the application fixed (e.g. it's 3rd party application).
See Inno Setup - How to set permissions of installation folder.
Even more gross workaround is to configure the application to be executed with elevated (Administrator) privileges.
See Inno Setup desktop shortcut (link) which has "Run as administrator" advanced property set
or How to set 'Run as administrator' on a file using Inno Setup.
Another solution is enabling legacy compatibility mode that makes Windows redirect all application write attempts to a virtual store. See also Application installed with Inno Setup writes files to unknown location instead of its installation folder.
There are numerous other possible reasons, why the application might be failing when installed, including:
You omitted some dependency:
DLL library
.NET assembly
.NET Framework
Java Runtime Environment
other runtime
COM/ActiveX object, etc.
The application requires some configuration:
a file
a registry key [including COM/ActiveX object registration]
an environment variable, etc.
The application is not designed to be executed from a folder that has a space in its name (Program Files).
The application gets confused by Windows File virtualization (though it's unlikely). See Application installed with Inno Setup writes files to unknown location instead of its installation folder.

The app I work on is written mainly in VB6.
Some users report that when they start up my app a different MSI installer will automatically run and try to repair its own installation. Often this is for AutoCAD but sometimes other programs also.
Usually this occurs every time they start the app.
What is a procedure that we can use to diagnose why this occurs? Since it is a third-party's installer which is running we don't have any visibility into what it is doing.
AutoDesk does have some info published on this:
Unexpected installer launches
Windows Installer displayed unexpectedly
but these do not directly provide enough information. Ideally I want to be able to completely prevent this from occurring to my end users, rather than just telling them how to avoid it or clean it up.
Your installer is acting on a directory, file or registry key that Windows Installer knows is part of the AutoCad installation.
First, I would turn on global Windows Installer logging. This means that any Windows Installer activity - including AutoCad's installer - is written to an external log file (in %temp%).
How to Enable Windows Installer Logging
Next, run your installer, and let the AutoCad installer run.
Now go to %temp% and you should find files MSIXXXX.LOG - one for your installer, one for AutoCad. Open these and you can work your way through them and identify which file or registry key the AutoCad MSI find is missing or changed.
You may find WiLogUtl.exe helpful for this:
Wilogutl.exe
With any luck you will identify that the directory, file or registry key triggering autorepair is also in your installer. If you're really in luck you can identify it as an item you should not be installing anyway - perhaps you are referencing a system component that would be present anyway, something protected by Windows File Protection.
If not, you will have to look at something like RegFree COM to move files out of shared directories into your private directory and reduce registry conflicts. Also, if you are using (consuming) the Visual C++ Runtime MSMs to make your MSI, consider using the Microsoft EXE installer instead or (best of all) placing the DLLs directly in your program folder, since I've found that the MSMs can cause just this sort of problem.
With regards to Peter Cooper Jr's comment on VB6 causing self-repair. Please check out the heat.exe documentation for Wix. You will see that there is a special switch the tool supports to suppress extracting certain registry values that are owned by the VB6 runtime itself (and hence shouldn't be messed with or updated by any other MSI): http://wixtoolset.org/documentation/manual/v3/overview/heat.html
Go down the list to the switch -svb6 and read the description to the right. (Reproduced here:)
When registering a COM component created in VB6 it adds registry
entries that are part of the VB6 runtime component:
CLSID{D5DE8D20-5BB8-11D1-A1E3-00A0C90F2731}
Typelib{EA544A21-C82D-11D1-A3E4-00A0C90AEA82}
Typelib{000204EF-0000-0000-C000-000000000046}
[as well as] Any Interfaces that reference these two type libraries
Does your installer write to these keys? If so try to exclude them - this is good to do even if it isn't the culprit in this particular case.
Other than that there is a lengthy description of what can cause Windows Installer self-repair here: How can I determine what causes repeated Windows Installer self-repair?. It is a long article because there are so many different ways self-repair can occur. The common denominator is that different installers on your system are fighting over a shared setting that they keep updating with their own values on each application launch in an endless loop.
I'm using PDFCreator to create PDFs in VB6. My VB6 development VM is Windows XP 32-bit. On that system PDF generation works both from a desktop app and from ASP (via VB web class runtime).
When I create an exe to run on Windows 7 or Windows Server 2008 R2 or use it in the web class runtime I get:
Run-time error '429':
ActiveX component can't create object
This is when using early binding. I add a project reference to "C:\Program Files\PDFCreator\PDFCreator.exe" and then in my code I do:
Public WithEvents mPDFCreator As PDFCreator.clsPDFCreator
Set mPDFCreator = New PDFCreator.clsPDFCreator
If I don't use a project references and use late binding instead, then it works on the desktop app but still not in the web class runtime. Late binding is done like so:
Set mPDFCreator = CreateObject("PDFCreator.clsPDFCreator")
I want to use early binding so that I can use the events, plus I need it to work in ASP/Web Class Runtime.
I realise I'm dealing with ancient technologies here and I should have tempered expectations when running such things on modern 64-bit Windows and IIS. If porting this legacy app to .NET were an option, I would.
On IIS I have set the Enable 32-bit Applications setting on my app pool. I have also tried running it as Administrator to rule-out security problems.
I've done everything I know how to debug this, but I'm stumped. I suspect it has something to do with PDFCreator being a 32-bit app and COM registration. I've also tried running regsvr32 out of SYSWOW64 but PDFCreator.exe can't be registered.
Windows 64-bit architecture does not allow the load of 32-bit dll into 64-bit processes.
But you can modify the configuration of your vb project to convert it from an in-process dll COM component into an out-of-process exe COM server. This will allow you to instantiate your 32-bit component from a 64-bit process.
See Process Interoperability
Since this is a VB6 question there aren't any 64-bit processes to worry about.
It seems far more likely than anything else that this library just isn't being registered properly. I haven't use it since I don't know whether its setup works properly. I do know that the download itself does not display with a UAC Shield on its icon, suspicious in itself. For all I know the setup program spawns a run of the wrong regsvr32.exe.
But it seems more likely you have misregistered the library manually after copying it naked over to these 64-bit Win7/Server 2008 systems.
In any case, going over all of the symptoms you describe, I'd guess it got registered as a 32-bit ActiveX library but registered in the per-user virtualized part of the registry for the user you were logged on as when you registered it.
This can be a hassle to clean up after. However you should, and then be sure to manually run the original setup once again with elevation.
These threads that include hand-wringing over "ancient technologies" really get old. It's a poor workman who blames his tools. In the future why not hire an experienced programmer to handle tasks like this?
I use PDFCreator in my accounting software written in VB6. Years ago, I noticed that after a certain update from the makers of PDFCreator, my software stopped working properly with it. The problem stopped after I re-installed the older version, and came back when yet another new update was released from them, so I have had my customers freeze at the version that worked. I don't know off the top of my head what version that was, but I can check my own web site since I made it downloadable for my customers if it would help, but it's likely many years old now.
Does anybody have any experience/ knowledge in installing the aspImage.dll on a 64-bit Windows 2008 platform?
I have a Classic ASP site that uses this component and would badly need to get the dll running. I have tried checking support documents for these to no avail.
Would really do appreciate your response.
Thank you!
Exactly the same problem migrating from server 2003 iis6 to server 2008 iis7 64 bit. Creating a new com+ application solved the problem.
I created the application I named aspimage using the com+ wizard as a server app, used local service for permissions, left default creator owner role alone, added users everyone and authenticated. After the folders were created, I added a component using the wizard. Already registered component, (assumes regsvr32 %systemroot%\syswow64\aspimage.dll ) and selected the check boxes 32 bit registry and details to ensure selection of the correct dll. Finish and the process worked. I hope this helps someone.
In general if you want to use a 32-bit COM object on a 64-bit machine you'll want to register the COM object use the regsvr32 executable located in the Windows\SysWOW64 folder. In IIS you'll want to go to the application pool advanced settings and select true for the Enable 32-bit Applications setting.
I know this is old, but I had similar problems this week:
To answer the question about registering, yes, you still have to run their registration tool and enter your license key. If using UAC, remember that both the regsvr32 and the aspimage's registration app must be run "as administrator".
I have managed to have the ServerObject aspImage.dll component run in a Windows 2008 64-bit platform server by creating a COM+ Application and using the aspImage.dll as a COM+ component.
I've also learned that any 32-bit components used in IIS that will be run in a 64-bt server needs to go through this process too.
For more details on delving on COM+ components and apps, please refer to this link: http://technet.microsoft.com/en-us/library/cc725986.aspx
Hope this helps!
