This issue has never happened on my previous installation of Adobe Reader, after downloading via the download manager, the installation process is detecting my F:\ to install, which is my external HDD and i have removed it from the USB port and tried again, it is still installing on F:\.
Then it shows "Error 1327 .Invalid Drive: F:\", which I don't have it connected, netiher do I wish to install it onto that drive.
Is there any other way of selecting to which drive I can install onto?
I had a similar problem: when installing Adobe reader via the doenload manager
I received an error message Invalid Drive F: (and nothing more)
My F: drive is a network drive mapped to a synology NAS.
After fooling around some time I discovered a map on my PC (C:\Users\Public\Desktop\Adobe 9 Reader-installatieprogramma) in which a setup.exe. Running this setup reveiled a somewhat more detailed error message: the error on the f: drive occurred when the setup program was trying to estimate free space.
In this map I also found a file AcroRead.msi. running this installer file installed the reader on my system.
