Help! Installer starts to install for customer then rolls back

(InstallShield 2011, Windows 7) For the (remote) customer, the installer puts up a message, "The installer was interrupted before xxx could be fully installed. Your system has not been modified. To complete installation at another time, please run setup again." The only time I've seen this is when attempting to run a 64-bit install on a 32 bit system or vice versa. But the customer assures us that he is running on a 64 bit system and is using our setup64.exe. How do you debug the installer, especially remotely? Of course, our setup64.exe runs fine on all our 64-bit Windows 7 computers. I have no idea how to reproduce the problem. Help!

I see that there is a /debuglog command line option which creates a log file. I also notice that even though my install is working correctly, the debug log reports "failures". For example:

11-8-2018[10:23:37 AM]: Extraction of '' failed

Does anybody know what betamarker.dat and evalmarker.dat are? Why does it try to extract ''?
Thanks for any reply..Is anybody out there?

  • Have you tried to disable the anti-virus or the security suite on the computer in question?
  • It could also be that the PC is malware infected and impossible to install on, or locked down in some unexpected fashion.
  • Even more commonly the setup.exe is corrupted and should be re-downloaded.
  • One exotic option is to try to install with a different admin account on the box in question (create new account if there is no such account). This is to avoid user profile corruption issues.

If I were to guess I would say the setup.exe is corrupted. Have them re-download first of all.


To create a log file see msifaq.com for more details (logging faq entry).


To find errors in the log file, search for "value 3" in the log file to find errors as explained by Rob Mensching (Wix & Orca author).

"The installer was interrupted before..." is a generic error message that is displayed when your setup fails for any reason. So you need to find the actual error message. Logging as recommended by Stein is a good start.

BetaMarker.dat and EvalMarker.dat may just be red herrings.
