Cannot preview PDF in Designer 8.1


Not applicable

I'd just recently installed FoxIt (an alternative to Adobe Reader) to test compatibilities and what are the limitations. It's good for viewing but not for dynamic PDF or even extended PDF.

It also seems that it corrupted the preview tab in the LC ES Designer and I cannot now preview my forms anymore directly. The LC ES designer, however, will open the browser to preview the form. the error message I'm getting when I try to preview or, even open a new documnet, is the following:

"There is a problem With Acrobat/reader. Please exit Adobe Acrobat/Reader and try again." Shortly after that LC ES Designer crashes!!!

How I can return my designer to it's initial state?

[Note1: I'm currently running Windows Vista and I have Adobe Reader 8.1 and Adobe Acrobat Professional 8.1]

[Note2: I have done the following in the shown order:

1. Uninstall FoxIt (I've test LC ES Designer again and the problem still exits)

2. Upgraded Reader to 8.1.1

3. Uninstall LC ES 8.1

4. Install Acrobat Professional 8.1

5. Install LC ES 8.1]

You help is highly appreciated.

I'd suggest uninstalling Reader, and reinstalling.

It sounds like FoxIt is hijacking some of Reader's registry entries. Upgrading Reader probably won't fix these, but uninstalling and reinstalling may.
