I see other threads describing problems. I have tried the install multiple times including on IE. Won't install.
Running Windows 7 64-bit
Please help
Same problem here. Recent install of Windows 8.1 64-bit. Have portable C++ and .NET 4.5 installed. Trying to run GarminExpressInstaller version 4.0.21.0 as Admin shows two GarminExpressInstaller processes very briefly in Process Explorer, and two instances of dllhost.exe which last a bit longer, then nothing. Clearly some other bit of software is missing.
