Hi
I upgraded my 4.5.5 site to latest 4.9.0 version

I got the following log:

My question is: did everything went well? I can log on to the site, current version shows 4.9.0 and it seems that site works OK.
Or should I first upgrade to 4.6.2 and then to 4.9.0?

Best regards & thanks a lot

Thanks a lot Sebastian!

The problems was during the installation .resources files, which you can find in.\Install folder, specifically in \Install\Package folder where are located ActiveDirectory_01.00.04_install.resources and CardSpace_01.00.00_Install.resources files. I deleted all files in this folder and upgrade didn't report any issues.

I'll install sepratelly these providers. Maybe some can check why the error happen.

Best regards
Goran
