InstallAware

I have an installer that works fine in most situations. I do have only a couple of customers reporting failure with below error and install log is absolutely no help at all. Am attaching both error screenshot and log. Can someone pls help me figure out what could be wrong or how I can go about debugging the issue?

Thanks

It looks a "not enough space error" when copying the setup data.

Is your project based on MSI (by default unless otherwise specified) or IA Native Engine?

Hello Francesco, Thanks for following up. I have not specified any native engine setting in my code, so I think it is whatever is the default.

Thanks

You should also check if any third party Anti Virus may be at root of the issue.

The error occurs at setup runtime initialization (when the engine tries to store the setup data on the target machine), but this fails immediatelly after ...and this seems to be due a process corruption. This is why you don't get any log.

I suspect an AV interference, honestly.

Thanks Francesco, Is there anything I can do to debug which AV could be interfering? The client claims that they don't have any AV and I don't have access to their systems.

Thanks

As first, I suggest you to verify the integrity of the setup package when this gets downloaded (I presume) on the target machine. Often third party AVs corrupt the files during the the download process.

For this, you may use the File Checksum Integrity Verifier utility as described here:

Hope this helps you.

Hi Francesco,
Yes I've confirmed that the download is not corrupted. Infact the other installers they got from us installed just fine, only 2 out of 7 are causing this error and am at a loss as to why.

Thanks

Hi Francesco, any idea how I can go about debugging this issue? See which AV could be interfering with the installation? The installer that's having trouble actually has 5 components (calls 5 different individual installers silently). 2 of them install fine but the rest fail and logs show as attached in the first post of this thread.

Thanks
MG

Unfortunately any THIRD PARTY AV may be potentially responsible of the isuue, and there is no way to debug it from the installer process ...due the fact that this gets corrupted.

The only option is with trying to replicate the problem on a test machine, and where you can compare the behaviour when the AV is installed/un-installed.

Optionally, you can also try with monitoring the setup process using the "Process Monitor" tool.
