Trying to use the Analysis and Solver add-ins. By selecting File/Options/Add-ins/Manage../Go then ticking "analysis", the Analysis add-in moves from the 'inactive' to the 'active' list but doesn't then appear in the Data tab. If I tick "solver" I get an error box telling me that it cannot access the solver.xlam file (and the Solver add-in stays in the inactive list). The xlam file does exist in the right location. Trying to add other add-ins gives the same result. Nothing added-in!
I saw one suggestion of an add-in installer bug. My %windows% folder is not "C:\WINDOWS" but C:\WINDOW2. However a registry search for the wrong CLSIDs didn't find anything.
