This issue has been reported to the Symantec Development team. Fixes about this process have been added to ITMS 8.0.
A pointfix is available for those that have installed ITMS 7.6 HF7. See attached "Pointfix_eTrack3907988_SMP_7_6_HF7.zip"
See the attached ReadMe.pdf for instructions on this pointfix.
In some rare cases, even with the mentioned fix mentioned here, you may need to verify the following:
Give your user (In our case, the «user» should be NS «App Identity») Full Access to the following folder: C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys (or C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys in previous OS versions).
We found that in some occasions the permissions in the machine keys directory needed to have the service account (App Identity) added instead of just administrators group:
Change security on directory:
Add your App Identity account, with the following minimum "Advanced" set of permissions:
Create files / write data
Create folders / append data
Write extended attributes
After hitting apply, accept that 5 directories were "Access is denied", if any.
