Some common issues that can be seen running 3DCalc:
1. The software does not start, showing a message like "Ordinal xxxx not found in mfc42.dll".
It means that the system files were not updated properly.
Possible reasons:
- The computer was not restarted after the installation program prompted to do so. In this case, 3DCalc (GemCalc) will run correctly next time your computer is started or rebooted.
- If you use 3DCalc (GemCalc) under Windows NT, this error can appear if the user which logged on does not have enough privileges to update system files.
Fix: run the installation again after making sure that you quit as many programs as possible, leaving only necessary ones. If it does not help, install the software logging as Administrator or another user with administrator access.
2. The software does not start, showing a message like "Cannot find opengl32.dll".
The problem is specific to earlier releases of Windows 95 (before so-called Windows 95 OSR2).
Fix: upgrade to a newer release of 3DCalc, which contains necessary files. Make sure you download "3DCalc for Windows 95". The files (opengl32.dll and glu32.dll for Windows 95) can be also received from Microsoft.
