When I install TM100 transponder key programmer software on Windows XP laptop, it gave me error “TM100.exe This program can’t start because mfc110u.dll is missing from your computer. Try reinstalling the program to fix the problem.”
You forget to install TM100 patch VC file.
Install VC file (Microsoft Visual C++) under Patch folder in the software CD.
If still not working, contact Gm-Tech2.com customer service to send you the TM100 key programmer patch file.
