Hello Tom,
This issue is an incompatible dll that comes from PGP 10.2.
Incompatible DLLs
Some programs (e.g. snapshot utilities) install DLL files which are automatically loaded when a program is started. Incompatible DLLs can prevent, abort or cause problems with the start of a program. To verify whether such DLLs exist, check the key
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > Windows
or, for 32Bit PGP on 64Bit Windows,
HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > Microsoft > Windows NT > CurrentVersion > Windows
in the registry. If the variable AppInit_DLLs is followed by an entry in this case (PGPmapih.dll), this DLL will be loaded at each program start. This can be prevented by either deleting the value of the variable (only the value, not the variable!), or setting the value of the variable LoadAppInit_DLLs to 0.
Here is a snapshot
This happened after the upgrade of PGG 10.2. I hae reproed this 4 times.
Issue is gone once steps are followed as explained above.
