New install Win 7 Pro. on Samsung SSD. Whilst trying to run compatibility troubleshooter on older software i get this error, details code 0x80070057
I've run chdsk /R C: and re-installed .net framework as suggested elsewhere but to no avail...
 
Tried everything I know, still the same. Actually manged to load the software in question as Windows recognised that it hadn't loaded properly, so the compatibility software works ok, just the troubleshooter not working on invitation... So, as at one point I'd had a system crash during installlation of an update I conclude that it ain't fixable by me so resort to a re-install and hope it works next time round... mebbe SSDs too fast for their own good!
