I can't get TSL to install... Running out of suggested fixes to try, and there's one suggested fix I couldn't even get as far as trying because it relies on the broken Scripted Diagnostics Native Host
Windows 7, with Scripted Diagnostics Native Host broken.
Further research has given me somewhat more hope for now, tho; I looked up this error specific to TSL and I found different solutions proposed than the generic ones for the same error.
