Sorry for posting this on the wrong forum before. 

Am running OS 9.1 on a 266hz/beige G3. 

Reader 5 was working fine since it was installed on a clean machine in 2/02. A couple of days ago I tried to open a newly downloaded .pdf file and the G3 froze. 

Tried to open the app on its own and it froze again. 

Tried to clean install a newly downloaded version of Reader 5 Installer from adobe.com. It freezes at the "finishing installation" point. 

Tried to install with extensions off and it shows an error -2,817. 

Have tried the following: 

Rebuilt desktop. 

Run TechToolPro 3 (Multi-tester from startup disk) twice. 

Trashed all found "Acrobat" "PDFViewer and "SVG" files many times between install attempts. 

Tried to install many versions of Reader 5 Installer from many sources including monolithic and installer discs. 

Have turned virus program off. 

System folder is not locked. 

File sharing is not on. 

I don't have any other versions of Reader on the computer. 

Have waited 30 minutes after apparent freeze to see if it's not really a freeze. 

The constant is it always freezes at the same "finishing installation" point. 

I did trash the offending .pdf file right away and every time I cleared the way for a new re-install I trashed all the items Sherlock 2 found for me for "Acrobat", "PDFViewer" and "SVG", including all prefs that came up from that search. 

Do anyone know of any other or hidden files I should trash as well? 

Or perhaps is it something really basic with the OS 9.1? Or some setting that I'm messing up? 

I haven't installed any software since the clean install in 2/02. 

Is there a way to download an earlier version of Reader? Would that do it? My MAC guy's out of ideas. 

I welcome any and all thoughts! 

Thanks in advance!
