Enhanced version question

[samssh]

Thank you both for your responses and effort. As for the installation, I followed the Win7 sticky instructions to the letter placing everything in a unique folder on the C drive. To make sure I just deleted everything and reinstalled to...

C:\Games\WinSPMBT

The CD installation file indicated it is V3 during the installation (top left of screen). After installation I installed all (up to 5.5) patches to...

C:\Games\WinSPMBT

Afterwards I tried starting the exe files with the following results:
MBT_APCalc and ARMORCALC both produce a message saying VCL50.BPL cannot be found.
Trying to open GAMEOPTIONS I get the message that DXANITIMER.DLL cannot be found.
In the utilities folder both OOB Converter and COSTCALCULATOR work ok.

Should I install all patches to this V3 file starting at patch V2.0?

Do you think purchasing a new download enhanced version will solve the problem? I assume the enhanced version available is the latest version 5.5.
