I'm trying to upgrade the Add-ons for episerver 7.5 via the deployment center. When I do so I recieve the following error:
Tilläggsprogrammet EPiServer Edit UI 3.0.1097 kräver att EPiServer (≥ 7.5 && < 8.0) är installerat
To even reach the initiation of this upgrade in deployment center I have to have episerver 7.5 installed, which I have. What does this error message really tell me?
I haven't done this via Deployment Center, but did you get upgraded site up and running with no issues? Sounds like to upgrade 3.0 version of shell UI it fails to load 7.5 assemblies.
It looks like your site was not upgraded before upgrading add-ons. This error message means that EPiServer Edit UI 3.0.1097 add-on requires EPiServer assembly version >= 7.5 and it seems that EPiServer assembly version on your site is < 7.5.Please use the following guide when upgrading a site from EPiServer 7 to EPiServer 7.5.
My guess is that old EPiServer platform assemblies were copied to the upgraded site when you rebuild your project. In this case you can remove that after-build events in you project that copy old assemblies on a site, rebuild the project again and restore latest assemblies in your bin folder.
