Hi - I've emailed support with this issue but in case anyone has any information prior to me hearing back from them it would be appreciated.
We implemented our software at a client yesterday on 10 XP Pro workstations. No problems except with 1 workstation. When accessing a screen using the VPE OCX, we receive an error:
Invalid class string
Error code: 0x800401f3
Aside from a locally installed runtime environment, the clients are all running our software from a network share mapped drive so there shouldn't be any kind of file corruption issue.
The language is Progress v9.1E.
