When i want to start Simulink, system prompted "Undefined variable "sltemplate" or class "sltemplat​e.ui.Start​Page.show"​"

I just installed Matlab 2016 in windows 7 system and I found I use Simulink. When I start simulink, it will prompt following error: Undefined variable "sltemplate" or class "sltemplate.ui.StartPage.show". By the way, I just upgrade my computer hardware, I don't know if this is the reason for this problem.

The default paths of MATLAB may not be configured properly on your workstation. In order to reset them, please proceed with the following steps:

 In MATLAB, type the commands to restore the application path
>> rehash toolboxcache
>> restoredefaultpath
>> matlabrc
>> savepath

Any custom path will be overwritten but you can make a backup as described in the article below:

How will running the restoredefaultpath and savepath commands affect my custom paths and how do I back up my custom paths? http://www.mathworks.com/matlabcentral/answers/166871

"restoredefaultpath" path will reset paths for all toolboxes/addons. This is why if you have installed a third party toolbox which doesn't come from MathWorks, you will have to reinstall that toolbox.

Thank you very much. Yes it does work.

[Gautam Sharma]

Thank you so so much. I just spent over 4 hrs banging my head to solve this

[Elodie Chatel]

I just did what described, and I still have the same errors...

[Theresa Cenate]

thankyou very much. It worked

[Akakan-Abasi Okon]

I am having issues trying to open simulink. Matlab is showing ''Error in sltemplate.ui.StartPage.show"

I've tried the precedures above but still didn't work.

[chris pang]

I have tried, it also doesn't work.

Dear Matlab Experts,

I get a similar issue after 2020b Update3

>> simulink

[...]

Error in sltemplate.ui.StartPage.show

Error in simulink (line 40) [...]

Unable to load bundle binary C:\LegacyApp\MATLAB\R2020b\bin\win64\builtins\sl_lib_browse2\mwsl_lib_browse2_builtinimpl.dll. Error: 126: not connected

I have tried other findings in the forum, nothing worked so far

The solution above does not work (for my error)

[anna friz]

I have the same problem, simulink won't open and it gives me this error

Unable to load bundle binary C:\Program Files (x86)\Matlab\bin\win64\builtins\sl_lib_browse2\mwsl_lib_browse2_builtinimpl.dll. Error: 126: not connected

still haven't found a solution
