trying to install cisco vpn client 4.8 on windows xp mce with SP2, I get half way through and I see: Error 1304 Error writing to file: C\\Windows\\system32\\vsdatant.sys, Verify that you have access to that directory.
wtf? so I tried re-setting the whole system32 folder to normal, still get the error. tried installing the vpn client via the msi file, still get the error. tried running as administrator, still get the error tried logging in as administrator (with password) and installing from there, still get the error did a search on google, haven't found a solution to this that worked for me.
