How to install the 1.9.1 update patch...

[Fizwalker]

I have version 1.9.0 installed currently and I downloaded the 1.9.0-1.9.1 patch. Upon openning the patch it asks for the location of my KSP install. I selected the location of my install and click "Next" The installer returns with "Please Select a Valid Kerbal Space Program Folder."  Is there something I am doing wrong?

 

Thank you for your time!

 

Location of the install: C:\KSP\KSP 1.9

It was a reported problem https://bugs.kerbalspaceprogram.com/issues/24944  They (Squad) think they have it fixed, so you might try again if the patch you tried is older than their reported fix.  Otherwise, the only solution I know is to download the whole 1GByte 1.9.1, sadly.
