Hi
I have a computer that I wanted to install math type on.
When I wanted to install the computer needed the original office disk.
I entered the disk but it was not the right version of office I am not sure why.
Sence I have a license version I decided to install the version that I have the license 4 and then uninstall the other one.
When I tryed to install I got a message that the source is not in e: now the cd was mapped to f: so I changed the letter of the drive.
Now I went through the installation and wanted to install the program in d: but it just said there is not enough room on the marked device but it marked is the cd (e:). I played around and it installed it via my usb drive ( I copied the source to it)
The program is running right. Every time I open a new document it opens like a new installation.
I still cant install the math type.
Also I noticed that the label on c: is blue.
Now this computer has been a bit of trouble seince the beginning.
Any help would be great
