A. THE BUG/ISSUE (Varies from issue to issue)
Can U reproduce the problem & if so how reliably?:
Yes. Every time - even during install of 64-bit version of Office 365 - perfboost.exe errors on this exception code.
Happens even if firewall,hips,sandbos, and antivirus are in the “disabled” state.
(Installs and runs fine if comodo is uninstalled)
If U can, exact steps to reproduce. If not, exactly what U did & what happened:
1: Install Office 365 64-bit Home version (does not happen with the 32-bit version)
2: Run any Office application (Word/Excel/Powerpoint)
One or two sentences explaining what actually happened:
Office 365 applications fail you start and report exception 0xc0000005.
The error log states AppVIsvSubsystem64.dll as the source of the exception
One or two sentences explaining what you expected to happen:
Excel/Powerpoint/Word should start normally
If a software compatibility problem have you tried the conflict FAQ?:
Not sure what that is - Does not seem relevant and a search did not reveal anything for “conflict faq”
Any software except CIS/OS involved? If so - name, & exact version:
Microsoft Office 365 64-bit (version 15.0.4631.1004)
From the logs, the actual culprit is AppVIsvSubsystem64.dll (version 188.8.131.52)
Any other information, eg your guess at the cause, how U tried to fix it etc:
Problem disappears if Comodo is uninstalled (excel/etc. start fine)
Problem disappears if Microsoft Office 365 32-bit is installed instead of the 64-bit version.
Problem persists if all of the modules of Comodo are disabled.
Based on the error, this is probably some sort of memory-access fault that Comodo limits.
Based on my reading it seems related to https://forums.comodo.com/defense-sandbox-help-cis-b136.0/-t100248.0.html - but that one is not in the Bugs forum, the problem is not restricted to Outlook, and the author does not specify they are using the 64-bit version of Office.
