I have a VOSTRO 1720 with 64 bit, with Windows 7 Ultimate. When I try to update Adobe or many other programs like LogMeIn, I get the same install error.

See unexpected installation error -203 when installing add-ons.

An alternative method of installing Adobe Flash is to use the manual installers. For details see http://kb2.adobe.com/cps/191/tn_19166.html#main_ManualInstaller
