Its important that I let you guys know that I had issues even in FSX with this. It completely messed up both sims. I know that Umberto has been saying that its not possible but the 2013 add on manager is working with no stackhash CTD on start up.
I never said "it's not possible". How I could post a fix otherwise ? I said that it's nothing *caused* by the Addon Manager, because up to today, the version using the 2005 runtimes always worked for years.
Something must have changed, possibly caused by a recent Windows update or by some other popular FSX addon that has been updated (or a combination of the two) resulting in issues when modules using both the 2005 are running *together* with modules running other versions, and the Addon Manager was the VICTIM of this, not the cause.
That's why, without changing a single line of code in it, but just compiling it with VS 2013, seems to have fixed all issues, because it now relies on the 2013 runtime libraries, instead of the 2005 ones which, strangely enough, are used by FSX itself, which was the main reason why we stayed with it until now.
