Visual Basic and other applications don't start anymore after MS Windows update
It seems that recently Microsoft rolled out some new updates, among which one of them is related to a vulnerability in MSCOMCTL.OCX related to the RTF file handling. It might seem minor, but as a consequence the OCX file got fixed and it is not registered anymore.
In order to fix it, you have to run one of the following commands:
- regsvr32 c:\windows\system32\mscomctl.ocx
- regsvr32 c:\windows\syswow64\mscomctl.ocx
depending on the operating system's bitness (either 32 or 64 bits).
