Problem with Internet Connectivity

Questions
1

I have a problem with Internet Connectivity of Mathematica.

From my notebook at home (one year home licence running on Win 7) is no a problem to get Astronomical Data.
But on my work PC (win Vista 64 bit) the same notebook doest work with a message

“Internet download of data for \!\(\“AstronomicalData\”\) failed”

The Test Internet Connectivity failed with a message “An error occurred attempting to update paclet information from site http://pacletserver.wolfram.com. Failed writing received data to disk/application”

Chanegs of proxy, temporaly firewall shutdown or start with clean preferences doesn’t help.

Please, do you have any idea whats wrong?

Thanks!

This issue may occur with certain paths containing diacritics. Try changing your $UserBaseDirectory to something with only regular ASCII characters (s instead of š etc.)

Thank You Ilian, but I seems not working -- see below

In[1]:= AstronomicalData["Planet"]

AstronomicalData::dlfail: Internet download of data for AstronomicalData failed. Use Help > Internet Connectivity... to test or reconfigure internet connectivity. >>

Out[1]= $Failed

In[2]:= Evaluate[$UserBaseDirectory]

Out[2]= "C:\\Users\\Tomáš\\AppData\\Roaming\\Mathematica"

In[3]:= $UserBaseDirectory = \

"c:\\Users\\TomasMathematica\\AppData\\Roaming\\Mathematica"

Out[3]= "c:\\Users\\TomasMathematica\\AppData\\Roaming\\Mathematica"

In[4]:= Evaluate[$UserBaseDirectory]

Out[4]= "c:\\Users\\TomasMathematica\\AppData\\Roaming\\Mathematica"

In[5]:= AstronomicalData["Planet"]

During evaluation of In[5]:= AstronomicalData::dlfail: Internet download of data for AstronomicalData failed. Use Help > Internet Connectivity... to test or reconfigure internet connectivity. >>

Out[5]= $Failed

I don’t know, why the second line in the code is so long and contain blue characters, in fact I can see in thne notebook only the message “AstronomicalData::dlfail: Internet download of data for AstronomicalData failed. Use Help > Internet Connectivity… to test or reconfigure internet connectivity. >>”, but this became here after CTRL-A, CTRL-C, CTRL-V… sorry..

Perhaps the old $UserBaseDirectory was still on the $Path. What about logging in as the TomasMathematica user and then starting Mathematica?

I’ll try to contact our administrator to change my login name to the syetem… I hope it will not affect othe my sw…

Actually I’d try first setting the environment variable MATHEMATICA_USERBASE and then starting Mathematica.

I set the variable to c:\Users\TomasMathematica\AppData\Roaming\Mathematica - the result is below

In[1]:= AstronomicalData["Planet"] 
 
During evaluation of In[1]:= AstronomicalData::dlfail: Internet download of data for AstronomicalData failed. Use Help > Internet Connectivity... to test or reconfigure internet connectivity. >> 
 
Out[1]= $Failed 
 
In[2]:= Evaluate[$UserBaseDirectory] 
 
Out[2]= "c:\\Users\\TomasMathematica\\AppData\\Roaming\\Mathematica"

At thle last step I tried to start Mathematica as Administrator -- and It works!

Thank you very much, Ilian!

Glad to hear it worked! The last step was probably necessary because Windows uses special permissions for C:\Users\…, and could be avoided by choosing a different location.
