Multiple installs of Acrobat, IE6-8 Javascript locations???

No.
This is just another reason not to have multiple versions of Acrobat/Reader installed on your machine.

Unfortunately, these residual folders left around are the result of Adobe not cleaning itself up after upgrades or uninstalls.

Let me put it another way...is there a DEFINED way to tell IE browser to ONLY USE Acrobat Reader to open PDF's in the browser, because even under the browser MANAGE ADD-ONS area, using Acrobat Reader 9.2, the internal plugins in IE are showing as Acrobat Pro 8.1.3.

My suggestion is to uninstall both Reader and Acrobat, run the Windows installation cleanup utility, manually remove any remaining folders, and then install only Acrobat or only Reader.

I absolutely agree...but in an environment where we're talking about hundreds, maybe thousands of end-users, this isn't always possible.

I guess the bottom line would be...is there a way to better control the version being used by the IE plugin?

Thanks for your input.

In Acrobat 8 and earlier, it was the current running version that was picked up by the browser. This was great for debug since you could easily control which Acrobat/Reader was used in the browser by just starting it up. But in Acrobat 9 this all changed. Now it depends on a registry setting.

See this tech note:

Having Acrobat 8 and Reader 9 on the same system is probably not too unusual, but I'd think that this might cause oddities in operation. Don't know how will work out with the registry setting.
