But priors at https://www.google.com/search?q=The+program+can%27t+start+because+api-ms-win-crt-runtime-|1-1-0.dll+is+missing+from+your+computer&ie=utf-8&oe=utf-8 tell another story.
However, I'd hit the Tortoisesvn forum for more spot on help. Beware you may get some flames if it's another Windows issue.
I don't think this is specific to tortoise. I've encountered mentions of C++ redistributable needing installed so I installed the one for Visual Studio 2013 but it doesn't help. Error is:
"The program can't start because api-ms-win-crt-runtime-|1-1-0.dll is missing from your computer".
This is running on a Win7 32 bit Pro VirtualBox VM hosted on Win7 64 Pro host. The VM does not get Windows Updates. It searches for them forever.
