Flash 10 on Windows XP – Insufficient disk space!?
Its been a while since I booted into Windows XP on my desktop. Today I did. Since Adobe Flash Player 10 is out, I decided to upgrade the existing flash installation – In fact, my bank’s website won’t work without the upgrade. I downloaded the installer and started it, only to get an error:
You do not have sufficient disk space to complete this installation. Please free 5000 KB and try again.
My disk is nowhere close to being full. A little Googling pointed at a known bug in the installer – Apparently, the installer has C:\ hard coded in its installation path. So if your boot/system drive is not C:\, the installer dies with a very misleading message, quoted above.
I tried to follow the workaround suggested for Windows XP, but it did not quite work, since Changing the drive letter of the system volume or the boot volume is not a built-in feature of the Disk Management snap-in.
Further Googling pointed at a very simple solution. All you need to do is map C: to an existing folder (G:\ in my case). So I opened the Command Prompt, and executed the following command:
subst C: G:\
There. I started the installer again and had no problem this time!
Way to go Adobe..
PS: Don’t ask me how I ended up having G: as the system drive instead of the standard C:.
