Solution
This is usually caused by mismatched DLL versions.
This error is usually resolved by removing any duplicates of pbvmxxx.dll on the machine or if the pbvmxxx.dll is missing.
The pbvmxxx.dll should be in the Shared\PowerBuilder folder.
However, in this scenario, the cause of the error was a mismatched DLL version of the pbshrxxx.dll. An older duplicate version was in the C:\Windows\SysWow64 and was removed. The pbvmxxx.dll has a dependency on the pbshrxxx.dll.
