FP 10.0.45.2 Firefox plugin won't install on 64-bit Win 7 Home Premium
Today I encountered exactly the same error that others have been reporting.
I am running Windows 7 Home Premium, 64-bit, but I'm also running 32-bit Firefox. (Since the vast majority of legacy software is 32-bit, there's no way anyone would buy a 64-bit system unless it could run applications in 32-bit mode.)
Flash Player was working in Firefox just fine this morning. However, this afternoon I got a message saying I needed to update it.
I went through all the usual difficulties with Adobe dowload manager, getting the special Uninstall Flash application downloaded and running, then doing a manual download and install of FlashPlayer 10.0.45.2, which Adobe shows as the correct version to run. (Adobe pages that won't load a second time in Firefox can be loaded after restarting the browser, which indicates the Adobe Web folks have some things issues to correct as well.)
Flash Player now works just fine in IE, but Firefox sends me off to another Adobe page that shows a Lego icon to click to download the Firefox plugin. (Remember, this is all 32-bit stuff here. I'm just replacing the prior plugin.)
The process downloads FP_PL_PFS_INSTALLER.exe into my temp directory (C:\Users\<username>\AppData\Local\Temp), but it dies with the above mentioned "The specifiied procedure could not be found" error. (Every time you retry, it appends a number to the end of the file name, so your error message would show the file name end with "...-2.exe" after the second attempt.)
Bottom line: the updated Flash Player is working in IE, but the Firefox plugin install routine is definitely (and consistently) broken on Win 7 Home Premium.
And there's no way to "revert" to a prior plugin, so don't consider this issue resolved until the install process works on our systems.
