I just hit a problem with a customer.   A third party tool they were using (and had no available support for) insisted on using Adobe Acrobat 11.  The computer had been automatically upgraded to Acrobat DC and the third party tool had stopped working.

Easy, I’ll just download Adobe Reader 11 I thought?  Not so easy!   It took a while, but I found an Adobe FTP site which has all versions of Adobe Reader – both old and new!

So here it is in case you need it:

ftp://ftp.adobe.com/pub/adobe/reader/
