Update.exe is Hanging Rarely

[invalidptr]

Update.exe works most of the time. But there are occasions when it does not in the field and it has taken us a long time to capture it in the lab. I have a VM exhibiting this problem now in our lab.

Update.exe is launched by our Windows Service when it is notified by our cloud to do so. Eg. command line:

Code: Select all

Update.exe /silentall -nofreqcheck -url http://example.net/download/update/Update%20for3.1.0.115.txt

If I look in the task manager update.exe is running and never exits. (msiexec.exe is also running)

A new update log file is emitted but I need assistance decoding it (attached). Does it give a clue as to why update is not working? If not, what other investigative steps do you recommend?

Also, I was surprised to find the update log file in c:\windows\temp and not in %temp% which in this case would be C:\Users\qaW7-64\AppData\Local\Temp.

Hello,

Please take a look on our "Launching AutoUpdater from service" thread which may be helpful for you.

All the best,

Note to future self:

* Add "/qn" to MSI Command line for the update build in bootstrapper. This will make it launch quiet with no UI.

* Change Extract Location in bootstrapper from "[AppDataFolder][|Manufacturer]\[|ProductName] [|ProductVersion]\install" to " [TempFolder]\[|ProductName] [|ProductVersion]\install". The Windows service does not have access to [AppDataFolder].

So this remains problematic for us when running as a service under Win7 64-bit.

[TempFolder]\[|ProductName] [|ProductVersion]\install is resulting in: c:\windows\temp\install (without any of the parameters).

We didn't see this until now because it requires an Install 1.0 -> Update to 1.1 and then the second Update to 1.2 fails. Because we're running into this problem.

Hello,

I'm not sure why this happens. Please keep in mind that the above extraction path should be resolved to:

Code: Select all

C:\DOCUME~1\<user>\LOCALS~1\Temp\Your Application 1.0.0\install

on Windows XP target machines, and to:

Code: Select all

C:\Users\<user>\AppData\Local\Temp\Your Application 1.0.0\install

on Vista or above target machines.

So, can you check the above locations to see if the extraction mechanism works?

All the best,
Daniel
