Yesterday I formatted my computer and did fresh install as it was due from long time. After the fresh install when I tried to install Semantic Search application using powershell, I was stopped by following error.
File cannot be loaded because the execution of scripts is disabled on this system. Please see “get-help about_signing” for more details

Fix/Solution/Workaround:
The solution is very simple. Open the Powershell window and type following two lines and everything will fine right after that.
Set-ExecutionPolicy Unrestricted Set-ExecutionPolicy RemoteSigned

Again, this is I have done for my environment where I am very careful what I will run. You can change the policy back to original restricted policy if you want to restrict future execution of the powershell scripts.
Simple – isn’t it? Well all complex looking problems are very simple to solve.

I think, by executing the command “Set-ExecutionPolicy Unrestricted”, we can execute all the required powershell commands.
Sir, is it mandate to run both the commands?
Thanks a lot ! it fixed my issue.
Hey Dave, Your blog is awesome. :)
For running scripts in powershell you only need one of the set-executionpolicy statements. Running the second one overwrites the first.
Try:
set-executionpolicy unrestricted
get-executionpolicy
set-exectuionpolicy remotesigned
get-executionpolicy
set-executionpolicy restricted
get-executionpolicy
you will see they overwrite.
Both will work to run scripts.
set-executionpolicy unrestricted will allow all to run
set-exectuionpolicy remotesigned will allow all local scripts to run but require remote scripts to be signed.
set-exectuionpoliciy restricted allows none.
Hi ,
I am running some code for this in ASP.net and facing same error as above . but same code is running and executing powershell from windows (winform) application .
