Hi, trying to install FP 11.7.700.169 on Imac OSX 10.6.8 with Safari 5.1.9.  Have tried on numerous occasions over days. Downloads fine, click on icon, installs, says installed successfully.  When I go to site requiring it, prompts me to install latest version.  On adobe site, no FP shown on my computer.  No error messages.  Have closed browser, switched off firewall, used Adobe Uninstall to ....... uninstall.  Got rid of files as advised elswhere related to preivous versions of FP.  Have spent ages trying to sort this out...  If somebody can help,  I can stop tearing my hair out and eating too many sweets! Hope this has given enough info.
