Start up problem - "initializing" takes ages...

Starting Matlab (7.11.0; R2010b) takes ages on my HP Pavilion dm1 laptop running on Windows 7.

I have tried several suggested solutions (add license path to Windows, check if toolbox cache enabled, etc), but nothing seems to help.

Below is the log i created with running "matlab -timing". It seems like matlabpath or matlabrc takes very long. However, if i rerun matlabpath and matlabrc after i get a prompt, they only take about 0.1 sec to execute..

Any help on this would be appreciated. Thanks.

Why not try the latest release? It might get rid of your long startup time.

I have been experiencing the same problem with different Matlab versions, academic and trial licenses, etc. I have searched forums for solutions and tried suggestions. As Ronald, I haven´t been able to sort this out. Can somebody help us, please??

You can add some TIC/TOCs to the matlabrx.m file to find out where the time is spent.
