The service account or user has access to all files. I checked the css. Not sure what is causing this error.
For the benefit of other readers, based on the Case she opened with Support, the issue was specific to the account Apruva was using. She logged in with another admin account (same account that was used by the service) and got past the Access Denied issue.
Open the "Details" in the message, and post it to this thread so we can see what it says.
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.
