What causes this warning and what can I do to keep it from popping up when my app installs?
Possible causes:
Virus scanning software (I'm looking into that)
Not putting the uninstall in the Add/Remove programs (this will definitely cause the problem, per documentation from Microsoft (see answer below)
Putting .ocx or .dll files in the App Directory?
Not registering the library files (app runs fine without reinstalling, so I don't think this is it.
Any other ideas?
To fix this, see this blog post by Aaron Stebner:
Your app is probably being detected by the PCA (Program Compatibility Assistant) as a non-Vista (pre-Vista) installation application.
You will need to add an embedded manifest and set a requested execution level
There is a previous stack question on this topic as well with some alternative work-arounds (noob, I can only post one link at the moment). You should be able to find some information on Vista-aware installation applications and be able to resolve this issue, but the info above has worked for me in the past.
One of the reasons this pops up is that after running the installer, the system checks to see if something changed in the installed programs list. If the contents of the installed programs list hasn't changed, it assumes that your application failed to install correctly.
I think this is related to operations which may be denied via UAC. (Not sure what exactly - file copies to restricted areas?)
To keep this from occurring, run the installer as an administrator.

When I ran the file setup_fmw_12.2.1.3.0_fr_win64.exe,
it gave me an error "Cannot launch the installer (555)".

Even though this relates to the installation of a developer tool, most would consider this particular type of question as generally off topic for stackoverflow. Your question also contains too little information to determine what the problem really is.
However, let's just mention some obvious things to see if it helps you solve your own problem:
Did you try the setup on another computer (or a virtual machine). This could be a good way to avoid the whole problem rather than spending a lot of time trying to fix it.
Did you locate any log files for the failed install?
A quick look seems to indicate that you can find log files at: %SystemDrive%\Program Files\Oracle\Inventory\logs (%SystemDrive% is normally C:\).
Or %SystemDrive%\Program Files (x86)\Oracle\Inventory\logs for 32bit installers on 64 bit systems).
Found in the troubleshoot section here - have a look yourself too - read from the top.
And the most obvious of all: did you contact Oracle support or search their user community or knowledge bases? Somebody will have seen this problem before. Looks like you need to register: https://support.oracle.com/
A quick search reveals that the Oracle Universal Installer is a Java based installer. Could Java be broken on the box you install on? (looks like the launcher should install the runtime automatically, but this could fail due to special conditions on the box. Try on a clean virtual machine). How to check whether java is installed on the computer.
Try disabling your anti-virus as well before running the setup on the problem box. Some setups even try to access the Internet during installation, and then your firewall could be a problem too. I would hate to turn that off though.
I built a Lazarus program and it's now in exe form.
I am able to run it on two of my computers running XP and Vista.
However, there are other computers as well running XP, Vista and Win7 but I cannot get it to run at all on them.
There are no errors, nothing... Has anyone else had this issue?
The program is connecting to a postgres DB on my LAN server.
Any idea on fixing this is really valued.
NEW INFO:
Maybe I'm wrong but here's a thought... On the development machine, I initially got an error like **libpq.dll* not found when I first tried to connect to postgres. Then after setting the path, it was fine. I'm thinking now if it cannot find that library and that's why it's not able to run.
If this is the case, should my line Application.OnException:=#CatchErr; catch the error? If not how else should I check if this dll or anything else is missing?
First, a sincere and big THANK YOU to Marco and MArtyn for the great tips and guidelines hat got me thinking of this strange issue.
Here's what happened...
I installed a fresh copy of Windows 7 and XP. As usual it did not work.
Then I suspected the old problem of libpq and then I copied libpq.dll from my working OS and put it in the application folder. By the way this machine has no Lazarus or Postgres. The moment I did this, I got my first error message saying that msvcr100.dll was missing.
And then I copied that as well. So the cycle of copy pasting went on for each and every error until I had finally brought these files to my 'non-working'.
libpq.dll - 9.2.1.12263 - PosgreSQL Access Library
msvcr100.dll - 10.0.40219.1 - Microsoft C Runtime Library
ssleay32.dll - 1.0.1.2 - OpenSSL Shared Library
libeay32.dll - 1.0.1.2 OpenSSL Shared Library
libintl.dll - 0.18.1.0 - LGPLed libintl for Windows NT/2000/XP/Vista/7
Once these files came in, the problem was gone!
Now the program works great :)
Thanks for all your inputs!
I now have to see what the above files have to say about their licenses as I have to distribute the app to other users. But I'm glad at least we figured out the problem.
No, base Lazarus programs don't require special permissions. Of course it could be that a specific functionality in the program requires special permissions (like access to ports below 1024, access to certain paths etc).
Also be aware that EXE's downloaded from what the system considers insecure sources (internet, certain kinds of shares) might be blocked by default. If that is the case, if you take the properties of the .EXE in windows explorer, there will be an "unblock" button.
Anything network related of course requires proper configuration of the firewall. The popups that query you might not always come, in case of doubt configure the firewall manually.
I got a weird problem with my VB app that has got me very confused. I am updating an existing program. I had to add some processing queue capabilities. On my system, unit testing worked great but when I compile it and run it on a different computer (a network server machine) it first tries to open an office install. If I cancel this, the program seems to run fine. The problem is that this program will be run in the background and I can't be hitting cancel each time it runs.
So my question is this: what is going on here? I'm usually a java developer we eclipse so I'm used to being able to include all the needed libs into the jar files automatically. It doesn't seem like the case with VB6. it seems like it expects all the same libs to be on all the systems. Is there any way to tell what might be triggering this?
The only thing I can think of that is causing it is that I'm using the "OpenProcess" function in the kernal32 lib. that the only major change I have made.
any help would be very appricated. thanks!
EDIT:
It seems that multiple versions of word were installed on the system and it was screwing things up somehow. We uninstalled one and it fixed it.
I ran into this a while ago and it was related to my installer for the VB6 app overwriting some system files for Office that it shouldn't have. Any time one of the System dlls was accessed Windows would determine that something was wrong and the Office installer would start up.
The short-term fix was to let the Office Installer repair the broken chain of dlls.
The long-term fix was to never overwrite built-in Windows System dlls.

Using VB6
i created a software in vb6 with xp operating system, In my system, software is working perfectly. When i run my software in other system(xp operating system), it showing error as cannot find project or library, showing error in Date, Left...,
Now i moved to vista operating system, i try to run my software, It showing the same error.
How to solve this issue.
My software is running in my system, when i try to run my software other system it showing error and also i try to run my software in vista also it showing a same error.
What happen in my code. There is any system32 file problem?
How to solve this issue.
Sounds like you need to create an installation for your VB6 project, to install the VB6 runtime and any non-standard components used. The runtime should be present by default on Vista, so it's probably non-standard components that are missing.
Consult the answers to your own previous question in August, when you asked how to make an installation for a VB6 program. (Even that August question was already a duplicate.)
You need to also copy the controls, and referenced files to the machine running your code. Some controls and referenced files will already be on the machine, but without experience you generally will not know which files are already installed. You can look at the checked files in the Project|References and Projects|Components dialogs to see what is included in your project. You will need to scroll through the components dialog to find all referenced files, but in the references dialog all the references are organized at the top. Also, to confirm what file(s) a machine is missing you can look at the Events log. An error with the missing file will be logged. A drawback of this approach is that you will only get one missing file at a time as the Application quits on the first missing reference encountered.
Also MarkJ and Konamiman are both correct in that the VB6 runtimes are required, although it is common for other VB6 programs to have already installed it. If you are not building in-house applications you do not want to take anything granted and should build a complete install for your application.
The other computers must have the VB6 runtime in order to run applications generated with VB6. Maybe is this the problem?
The VB6 runtime can be donwloaded from here: http://www.microsoft.com/downloads/details.aspx?FamilyID=bf9a24f9-b5c5-48f4-8edd-cdf2d29a79d5&displaylang=en
Use the Package and Deployment Wizard to create a setup.exe. The Wizard will automatically include all the files you might need for distribution.
I have a VB6 app that formerly worked perfectly on a Vista machine as a scheduled task, but it will no longer open on the same machine. The app generates export files in a specified folder with no direct output on the screen. I get no errors, no missing references, just absolutely nothing.
The machine is running Vista Business 32-bit, UAC is disabled with a single administrator account, and automatic updates are turned off. The app resides in a non-protected folder, and the export files are put in a folder on the desktop. The client swears that the only change they made to that computer since I installed this app was installing Norton Antivirus, which has never caused problems before with our software.
In addition to the normal VB6 references, the app references Microsoft Scripting Runtime (scrrun.dll), and Microsoft DAO 3.6 (dao360.dll). Both of these files are present and registered on the target machine, along with all the other VB6 dependencies. I added MsgBox statements at the beginning of Sub Main() just to see if anything is being executed, and its not. Disabling Norton yielded no results, nor did reinstalling VB6 runtime to rule out any corrupted libraries. Not once did I get any messages, error or otherwise from my app.
I've never had an issue like this before and I'm completely stumped. Is there anything else that could be causing this?
Edit - The app does not run even when I run it manually, so the part about it being a scheduled task is irrelevant to my problem, sorry for including it.
The user has full administrator credentials, no compatibility mode was needed on the initial test which at the time, was done on this very machine I am having the problem on. For grins I tried compatibility mode for XP and 2000, still nothing.
Try to inspect - if you can access them - the Event Viewer messages. Maybe you will find some tell-tell signs in there...
You could try running the program in Windbg, a free standalone debugger from Microsoft. Compile your VB6 EXE into native code with symbols (create PDB files) and you will be able to debug your application in Windbg.
I would guess one of two things will happen.
Windbg will fail to load the EXE. Presumably with an error message that will identify your problem.
Windbg will load the EXE, and you can single-step through to see what happens.
Here's a 2006 blog post by a Microsoft guy about using Windbg with VB6, and 2004 blog post by another Microsoft VB guy with a brief introduction to Windbg.
Has the user changed their password? That will cause the scheduled task to fail until they re-enter the password on the task.
Have you tried running the process directly, instead of as a scheduled task? I'm far from an expert, but it may be that any errors being generated are not showing up because the program is running as a task.
