Sorry if that seems rambly, I'll focus on Windows 7 x86_64. When the install failed, there was no apparent error code. The installer only said that the software might be counterfit and the installer was exiting.

The log, at the end says:

Please search the above error/warning string(s) to find when the error occurred.

These errors resulted in installer Exit Code mentioned below.

Exit Code: 37 - Validation failed.

Please see specific errors and warnings for troubleshooting. For example, ERROR: DW049, DW050 ...

END - Installer Session

*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= *=*=*=*=*=*=*=*

There are 83 errors, which either say

validation failed

or

has an action "install" but no resultState

I can post the full log if it will be helpful, but it is quite long...

There are no fatal errors and 83 errors, most of the errors are like

ERROR: DW049: Payload {00496505-D56B-4B07-A8C5-70A0B4E689F7} Adobe Bridge CS6 (64 Bit) 5.0.0.0 has an action "install" but no resultState

There is one error that looks a little more promising

CS6 Suites Custom hook: Successfully Updated PCFClientFile and cache.db for Acrobat Professional 10.0

----------- Payload: {539AEF15-3A2B-4A31-A587-7E90F7D9C700} Camera Profiles Installer 7.0.0.0 -----------

ERROR: Payload '{539AEF15-3A2B-4A31-A587-7E90F7D9C700} Camera Profiles Installer 7.0.0.0' is corrupted. Sig file 'D:\Adobe CS6\payloads\AdobeCameraRawProfile7.0All\._Assets1_1.sig' is corrupted or not present.

I've navigated to that file (._Assets1_1.sig) and it appears fine in a text editor (i cannot verify the checksums, however). Still the most confusing part for me is why the same disk would work on other computers after the failed installation on this machine, but this machine keeps failing.

I tried searching for "validation failed," resultState, DW049, and Assets1_1.sig on the page at that link and there didn't seem to be any reference to those errors... is there somewhere with a more complete list of installer errors?

Googleing some of these terms brings me to links about cracking CS6, so maybe there is some corruption in the DRM files, but that doesn't explain why it would work on other computers after the coruption existed. I'm going to try a different DVD drive, maybe the one I was using is having trouble reading the disk...
