Gyana:

I am unable to reproduce this error and hence cannot pinpoint the cause. You have confirmed that all required DLLs are registered, user access rights are fully enabled, and you have tried alternate ISOGEN configurations. I have found reference to this issue occuring in some cases due to Virus software restrictions, you may want to explore your settings in that regard as well. Meanwhile I will continue to attempt reproducing this error on my end under above confirmed parameters and update you on any further findings.
