2017b: Since install of 2017b, I cannot run App designer properly. It fails to load something and does not compile.

Hello,

I installed 2017b and right after I could not use App Desinger anyloner. Also the previous project .mapp are not running anymore while they have been converted from 2017a.

Can someone have a look at the output with the error and advise for a solution?

Thanks.

[JClarcq]

I want to add that:

restoredefaultpath

did not solve anything.

Answer 2

[Chris Portal]

Can you try the following and see if that helps:

rehash toolboxcache

[JClarcq]

I did it. Still full errors. Look at output:
