Solar Fire 9 Forum

You need to find a working MFC40.DLL file to make Solar Fire v9 to work. This is part of the Microsoft Visual C++ 4.0 Redistributable, but I was unable to locate it online. Instead, I found an old version of Microsoft Visual C++ 4.0, and copied the MFC40.DLL from there. The Microsoft Visual C++ 4.2 DLL does NOT work with Solar Fire v9.

This is how I managed to install and run Solar Fire v9.x:

• Install as "Unlisted application"
• Select your Solar Fire installation EXE (I used "sd9025usa.exe")
• Use a Windows XP Bottle
• Add additional dependencies: Core Fonts
• I added NO other Visual C++ / Visual Basic runtimes are needed!

Once installed, I copied MFC40.DLL to the C:/Windows/System32 directory
I then ran "regsvr32 C:/Windows/System32/MFC40.DLL" to register the DLL.

Finally, I downloaded SolarFire_9.0.29_Patch_Asteroids.exe from the Astrolabe web site, and ran it to upgrade to the latest version.

The Solar Fire v9 application now runs fine on my M1 MacBook Pro.

Could you help me, please?

Thanks in advance.

The error message you mention seems like a Visual Basic error. Did you follow Johan's instructions (WinXP bottle, install the dependencies, install MFC40.DLL)?

Yes, I followed every step mentioned. Solar fire runs ok but i can´t work with it due this issue.
