Error in instalation

Hi, i'm having a problem instaling version 1.8ce

When I manually choose the folder to export to, the install option is not available, and when I the browse option, the OK is not available to confirm my folder selection. Even the default C:\Program Files\3ds Max folder wouldnt get the install option enabled.

I'm surely the PC's admin.
I guess (just a wild guess) that the problem is in the instalation size. I have 1.5GB free in C: and 3.2GB in E: , maybe, the installer compares the sizes in figures rather than size, i.e. 12.1MB and 3.2GB, it compares the 12.1 and 3.2 that's my guess anyways
Please help, thank you in advance

Do you mean the folder where to install to?

It should be the folder where max is installed, you cant install on another folder

Hi Lioric,
No I dont mean the folder to install to, I mean that whatever the folder I choose to install to, the install button is not enabled, so I cannot proceed!!

Point to where max is installed

I have the exact same problem! I try to browse to my install folder, but the OK button won't enable for me to choose it. I also have tried typing in the path manually, but the install button still won't enable. I have also tried rebooting and starting again, but still I can't get the OK button to work when browsing for the folder, or the Install button.
