@Amin_Yahyaabadi, Let me try to pinpoint the issue.
In my case not only they point to different Julia binary folder, they have different Base.DEPOT_PATH.
Yet, still something mix them to use the same BLAS although they shouldn’t be able to be aware of each other (Remember, each have its Environment Variable pointing to different paths).
I suggest you have a look on your installation and verify that indeed you different BLAS vendor on each.
I don’t want to use Julia’s binaries.
I’m old fashioned on this and I want a package which coherent form the producer. Different people will have different choice. Yet this is mine. Still it should work and something tricky I don’t understand happening here.
Let’s wait for an answer of someone who understand how Julia Pro sets some of its parameters. Specifically the Path. My indication (Since the folders are locked and I can’t delete them) that one of the processes doesn’t release the convhost.exe process. Which created a case when I launched them one after the other to “merge information”. Just a speculation.
We’ll have to patient until someone who is informed will explain.
