Addit! Pro For Combat Flight
Simulator 2
When I try to install an addon I get some weird run time error 430,
"Class does not support Automation or does not support expected interface".
If Addit! Pro reports run-time error 430, "Class does not support
Automation or does not support expected interface", the ActiveX system file
mscomctl.ocx could be the problem. That file might be damaged, incorrectly registered or
mismatched with the components Addit! Pro expects to find on your system.
Replacing mscomctl.ocx with the version from Addit! Pro's distribution may solve
this problem and restore Addit! Pro's functionality. Here is how to do it:
1. Download a fresh copy of Addit! Pro from ByteForge (http://www.byteforge.com/downloads). Be sure
the version you download is the same as the version you have installed.
2. Create a temporary folder on your hard drive (e.g. "C:\APTEMP\") and unzip
the contents of the Addit! Pro zip file to that folder.
3. Press the Windows Start button then select Search (or Find).
4. Search your Windows operating system drive for "mscomctl.ocx".
5. Once you locate your copy, which should be in your "\System32" folder (or
"\System" folder), move (not copy) the file to a new
temporary folder (e.g. "C:\PREVMSCOMCTL\").*
6. Start Addit! Pro. The Windows Installer should notice mscomctl.ocx is missing. It will
either restore the file automatically or, if it cannot find apfsx.msi (or apfs2004.msi), it will ask for the Addit! Pro distribution folder. In that case point it
to the folder you created in above (e.g. "C:\APTEMP\") then press OK.
The problem should be solved by these actions.
* Keep your original mscomctl.ocx file around for a while in case you notice problems with
other applications.
