We recently had a client that was on version 2016 of Sage 100, they also were on an older version of Sage Fixed Assets and needed to upgrade the Sage Fixed Assets to version 2018.1. Upon doing the upgrade they received the error “Unable to cast COM object…” in Sage 100, after install the Sage Fixed Assets Client 2018.1.
So, what is the cause of this and how can it be resolved?
The cause of this “Unable to cast COM object…” error lies in the Crystal Reports runtime version (SP21) which is installed with FAS 2018.1, SP21 is not compatible with Sage 100 versions 2017 versions and earlier.
To start with replace existing pvxwin32.exe.config located in the “2016” installation of Sage 100 Standard …\mas90\home\ with a copy of the same file from Sage 100 Standard 2018. The pvxwin32.exe.config new file can be obtained from Sage 100 Support.
Then visit all the Workstations that have Sage 100 and install the FAS client, that is the fix.
In addition, Sage Support did a great job documenting the fixes for other scenarios with different versions of older and newer Sage 100. The Knowledge Base Link is here.
