How can I find what's hanging all new installations on a Windows box?
While testing an installation script on Windows (XP Pro, if it matters) I've run into a situation wherein any and all attempts to install anything on the system hang waiting on who knows what. When the system is restarted, all queued up attempts at installation then go through their exit paths with pop-ups that report the installation is being aborted due to system shutdown having been requested. Of course, reboots do not cure the problem. The system otherwise runs fine.
So... How can I determine what part of the OS I've wedged? (Something in the registry, I suppose, but I'm a real greenhorn when it comes to Windows.) Most likely, something from a preceding install attempt went awry and is now blocking even though I saw no errors reported. Once I figure this out, I want to put in a check for this sort of thing, possibly at both ends of my install scripts, if that seems reasonable.
Thanks for your input.
UPDATE:
Unfortunately for me, rebuilding from scratch to get to the point the system's in now is about 9 hours. I'd like to unwedge it from where it is now rather than reload (again). Procmon seems great but I haven't got SP2 installed, only SP1! -frown- So, other ideas are welcome.
I assume you've tried logging the install to see where things go wrong?
Try rolling back to before things went wrong using "System Restore", if that doesn't solve it and the MSI log files show nothing useful then I'd take the plunge and reload before wasting any more time on it.
That said, if you're developing installers then taking an image of this PC in it's crappy state could be a worthwhile exercise. Some point in the future when you have more time to debug you can try and figure out what the problem is.
P.S. I'm assuming you're asking this question from the point of view of someone developing an installer and not as a tech-support question... otherwise this question should probably be closed as not-programming-related ;)
Try using Procmon to figure out where the installer is having problems, if you set a filter it will report all file and registry activity for that process.

the other day my little brother downloaded a game from somewhere, and as I caught him in the act of installing it, I noticed a little pop-up window in, like old windows graphics, popped up all sneaky and said "be now on auto start" or something close to that. So, is there any way I can find out what that was, where it is, or what it's doing, so I can see if it's a virus? thanks for your time and effort. the spell checker wont let me type v before "be on auto start"
There is no surefire way to locate an unknown .vbe file that is currently running. However, some detective work may be able to uncover its location. Try checking recently accessed files, running processes, and open network connections to see if any clues can be found.
While I'm using my computer a blue window will pop up for a second then go away. The label said windows power shell, I've tried looking at the event viewer but I could not identify anything there since I'm a new user. What could be causing this?
Running windows 10
Sometimes installed programs open up command prompts to run services/init tasks, so its not completely unusual.
I've never seen it happen with powershell however.
it could be innocent and just a program you have installed running init behavior, but it could also be malicious.
the first thing to try is checking what programs are set to startup automatically. if there is a load of bloat, you could try turning off the unnecessary ones and see if it still happens.
but realistically the only real way forward is to get a good quality antivirus, and run a full system scan over your pc to double check. it wont give you 100% certainly as things could possibly get passed it, but realistically if it passes you should be fine
Not a programming problem per se, but rather a programming environment problem that I have been unable to find a solution to.
The problem relates to Adobe's Extendscript Toolkit (both 3.5 and 4), but so far I haven't been able to solve the problem, so here I am...
The error I get has appeared more or less over night. I didn't experience this problem yesterday, nor this morning. But exactly WHAT has happened is beyond me. I have removed preferences, I have uninstalled, reinstalled, created a new user, restored old preferences from Time Machine and I'm now pretty much lost for options.
Basically, nothing works in ESTK anymore. Just opening ESTK and entering alert('Hello') won't work. Neither will $.writeln(). Everything running from within ESTK seems to give the same error;
Cannot execute script in target engine 'main'
With details:
Cannot execute script in target engine 'main'!
(#1116) Can't start debug session.
Below is a screenshot taken from the new user I created to test, same problem.
The "funny" thing is that all the scripts (InDesign CS5, still hanging on to it for reasons) still work perfectly in the applications' script panels. So there is nothing wrong with the scripts (heck, they haven't changed one bit, and still refuses to run in ESTK).
As mentioned, I've tried installing the ESTK CC (version 4) as well, but the very same problem occurs there. Which leads me to think the problem lies somewhere else, but I do not know where, and why.
So, if anyone can shed any light on this issue, at all, I would be very happy. Debugging is basically the only thing ESTK is good for in my book, but now that even that functionality is gone, I don't know how to efficiently debug the scripts which is kind of hampering the workflow.
For reference, I'm running InDesign CS5 (from the old Creative Suite) on a 2008 Mac Pro with 10.11.6 (El Capitan) installed. Well aware that it's pretty out of date, but that is beside the point here.
In the above mentioned forum, Adobe has published a stable workaround!You just have to correct a setting inside the estk application:
Open the file(Mac): “/Applications/Adobe ExtendScript Toolkit CC/ExtendScript Toolkit.app/Contents/SharedSupport/Required/cdic/11BTBackend.jsx”
Search for the value: 604800000 (line reads bt.timeout = 604800000)
Replace that value with 604800 and save
Quit ExtendScript Toolkit and relaunch.
I can confirm that it works.
From the adobe Forum :
"we have found a first workaround: just change your date to any date before 20-nov-2018"
https://forums.adobe.com/message/10761440#10761440
Seems like a date issue :(
I just published a quick update about this on the Adobe Tech Blog.
For the time being, if you dismiss the dialog, you can still run your script via ESTK and step through code as usual.
Alternatively, if you really want to avoid the dialogs, and you don’t mind setting your clock back, you can sidestep the issue by setting your system clock back to November 19, 2018 or before. On most systems, changing the system time can have unintended side effects, so this isn’t recommended unless you’re really certain about it.
I'm stuck trying to debug a problem which only occurs on my machine. It doesn't exhibit on any of the other devs' systems, nor on our production test server. I've tried pretty much everything I can think of short of completely wiping my hard disk and starting from scratch, or sneaking into the office in the middle of the night to swap my computer with someone else's.
This brings to mind the titular question, then: short of those drastic measures, what do you do when trying to resolve issues that no one else has? I'm open to advice that's general or specific.
[Not sure if this should be CW or not.]
Have you attached a debugger to the program to find the exact point of failure? That is what I would do first.
Sometimes third party software can be the root cause of these sorts of issues. Things like Anti-virus software install low-level filesystem and network drivers that can cause random intermittent failures. You can try killing all processes that aren't base OS services and your app.
Depending on your OS there are different tools that you can use to see what's going on under the covers. E.g. on Windows you can use Process Monitor to see what Registry keys it opens, what DLLs get loaded, etc. You can run this on your machine and on the success machines and compare to see if perhaps some required module is missing .
But seriously, use a debugger. That's what they are there for.
Two things:
I start with the obvious: What's different on your box? More memory? Odball PCI card? Different Microsoft APIs or service packs?
For oddball random software and/or OS crashes:
Check your system for heat issues.
Check your RAM for bad bits.
In this situation, I would try to check out the code and cleanly rebuild it from a different directory to make sure that there are no miscellaneous files in your working directory that are causing a problem.
If you are doing work against a database, I would also try tearing down the database and reconstructing it, possibly using a dump from another developer's machine.
Check the versions of any external third party software - database version, OS version, even software patches.
Look at the configuration on someone else's machine who doesn't have the problem and compare.
Get another developer to sit at your workstation and try to reproduce the problem and also go to their workstation and try it. True story - a fellow developer had a bug that he could only reproduce on his machine...it turns out that he was doing something slightly different in the GUI that no one else was doing (tabbing to a button and then hitting enter, everyone else just hit enter). It never occurred to him that other people might just hit enter to submit, because that "didn't make sense" to him.
Is there any "Boot session ID" or (reliable) "Boot timestamp"?
For an installation I need to detect that a scheduled reboot took place indeed.
I guess I could do a dummy MoveFileEx() with MOVEFILE_DELAY_UNTIL_REBOOT, but i did hope for something easier.
(We have to install a 3rd party package that sometimes behaves erratically after an repair/update. In that state, accessing the device may even lock up the system)
(Windows XP, Vista, 7)
For things like this, WMI (Windows Management Instrumentation) is often a good starting place. I know you can get current uptime directly through it, which may allow you to determine if a machine recently rebooted.
Here is a blog post with some code samples as well:
http://blogs.technet.com/heyscriptingguy/archive/2004/09/07/how-can-i-tell-if-a-server-has-rebooted.aspx
Depending on your implementation language, you probably just want to pull out the query code from the vbscript.
Apparently Windows has the equivalent of "uptime". Here's more info: http://support.microsoft.com/kb/555737
As I understand it, this should tell you how long ago the system was booted. Will that information solve your problem?
You could search the System event log for event 6009 from the EventLog source - this is the first event recorded after each reboot.
I think the best answer has already been given here: Find out if computer rebooted since the last time my program ran?
That seems to be the simplest way. Use GlobalFindAtom() to see if it exists and create it, with GlobalAddAtom(), if it doesn't. It will persist beyond the execution of your program. If your application runs again, and sees that the atom exists, then then it isn't the first run since reboot.
If the computer is restarted, then the atom won't exist, indicating that this is the first run of your program since the reboot.
