Now I installed the free pdf-Reader Foxit reader, because Acrobat always crashes.

Even information on why this cannot be done - would be appreciated so that he could use as a reference point to his clients.

Thank you for your prompt responses to this question - Please???

Cath - HELP!!!!!!!!!!!!!!!!!!!!!!!

Now, I can install Adobe 8.1 without getting an error that a higher version is already installed.

This may work for your problems.

I also tried to use Your Uninstaller 2008 to remove it but failed. This is my newly installad window XP with AMD X2 5000 and 2GB Ram.

They only know to get money but even the support also need money but they are help less. Always ask me to format computer. They are useless!!

Having nearly pulled all my hair out trying to get Acrobat 8.1 professional to run but kept coming up with the ’serious error, has to close - cannot write to memory’ etc, I found from a variety of forums and even Adobe’s web site, that this was a well-known problem.

After uninstalling and reinstalling a number of times and getting nowhere, I tried the following:
instead of uninstalling Acrobat through the control panel, I moved the Acrobat 8 folder to the recycling bin; uninstalled Adobe reader 6; cleared any remaining Adobe folders (I had an Adobe 5 folder hanging around) to the recyling bin, and also the two Adobe files in the Flexnet folder. Then I ran a registry checking program and let it sort out any errors.

I had another try at installing using a ‘typical’ install this time (other times had been ”complete’), and it went through without any problem, calling up the activation/registration page when first started.

(For info I run XP SP2 with 512M memory)

Adobe released a patch. it FIXED THE ISSUE for me. I was running Vista on a Dell Inspiron w/ AMD64 chip, Acrobat Standard 8.1:

Patch is here: http://www.adobe.com/support/downloads/detail.jsp?ftpID=3750

I ran the patch as administrator. It took about 90 sec and looked like it was stuck but finally command window disappeared. You don’t get a notification that it’s done, the window just disappears. See instructions beforehand, you’re supposed to stop the licensing service first, I forgot and it worked anyway. Reboot required after the patch. When you reboot and start it again, it prompts you to activate (it sends your lic key to Adobe). Hooray.

My problem is that I am creating forms in Acrobat 8 but users with Acrobat 6.0 do not get the input fields to complete the forms. Another user got the input fields but when the cursor is there, it does not let the user input data to the form.
