On one customer site, different work stations, latest version of OFM (v3.60.10) installed no errors.
Attempt to use > Processing > Submit to Government Gateway > 'any of the x5 selections' generates this error message:

Have tried:
- folder permissions
- install as local admin
- run as local admin
- reinstall
- tested on different PC's
- checked event log
- checked Infor knowledge base
Noted:
- program files directory lists HMRCMark.dll + HMRCMark.tlb
We have not seen before.
Any thoughts / suggestions appreciated.
Thanks
