Hi  
  
I am trying to install PTB. When I try to install subversion I get the error "The installation package could not be opened. Contact the application vedor to verify that this is a valid Windows Installer package."  
  
Any ideas?  
  
Also at the PTB site it says to install svn 1.6.9. However the current version is 1.6.17   
  
Best  
  
John

Oh, just read some notes in DownloadPsychoolbox:

stable has been renamed to unsupported, as its years old!So use beta, which isn't really beta at all, just the up-to-date version. Calling Psychtoolbox without the flavor specified should do the trick for you.

If not, please try again with DownloadPsychoolbox([],[],[],'beta')--assuming all the others can be left to their default (and do let us know if you didn't ask for stable by hand, the installer shouldn't do that by itself!)
