I actually came accross that article yesterday and tried deleting the Prefs file, but it didn't make any difference. I haven't tried running CC cleaner or manually deleting any mention of Adobe priemere in the registry yet... I was hoping I wouldn't have to go to that extent. The person in the link above, did all that and he still has the same problem, so the procedure is not instilling any confidence in me. Note: in the link above the person was running XP... I am running Windows 7 SP1, 64 bit. and I am installing a retail version from CD/DVD.
Moving this discussion to the Premiere Elements forum.
If you want to give some troubleshooting a try, I will stay with you until we get that Premiere Elements 11 Windows to work. I will have lot of questions because I believe the answers are in the details. Often I write problems with the same symptoms can (often do) have different causes. So, I look at each case for details specific to it.
1. How long have you been running Premiere Elements 11 Windows 7 64 bit without this problem: few days, few weeks, few months, never worked? The usual drill...do you have the latest version of QuickTime installed and are you working from a User Account with Administrative Privileges? Are your video and audio card drivers up to date?
2. What do your computer resources look like, available RAM, free hard drive space (derived from just Local Disk C or using a supplemental drive for scratch disks and video storage? Where are your scratch disks directed and how much free hard drive space is at that location? (See Edit Menu/Preferences/Scratch Disks.) Besides your ccleaner maintenance, have you checked for Adobe Folder previews and conformed audio pile ups? Have you cleaned the Media Cache Database (See Edit Menu/Preferences/Media/Media Cache Database.)?
3. You say the problem happened out of the blue. Any new software, plug-ins, codecs, and the like installed around the time that the problem set in?
4. I would like to see you get rid of the Welcome Screen as your point of entry to the program. To that end, right click the Premiere Elements 11 Desktop icon, select Properties, select Open File Location. That will take you to a file named Adobe Premiere Elements 11.exe. Select the file next to it named Adobe Premiere Elements.exe, create a Desktop shortcut to Adobe Premiere Elements.exe, and use that Desktop shortcut thereafter to open Premiere Elements 11.
5. I would also like to explore other ways of opening the Premiere Elements new project depending on results. One example...can you open a new Premiere Elements project from the Elements Organizer?
5. If possible, download and install the free 30 day tryout of Premiere Elements 11 Windows from Adobe and determine if that will install for you from the Premiere Elements as well as the Elements Organizer interfaces. Adobe allows only one download of its tryout product version whether you have used the product 1 or 30 days. So, if you have gone the tryout route, this idea isn't going to work unless Adobe makes an exception. But, I do like this idea for troubleshooting purposes.
MBolton never did follow up to a conclusion on the thread that kglad kindly referenced. There were other avenues to explore. I look forward to the opportunity to assist you in your Premiere Elements troubleshooting here. I am no longer visiting nor answering questions at the web site where MBolton and I sought to find an answer to this issue.
I found the SOLUTION!!
The Short Story... The problem got fixed when I found a fix for another problem I had. After a failed update of Adobe Reader about 8 months ago, I was unable to install any version of Adobe Reader and I have been useing a different PDF Reader since then. A co-worker's Adobe Reader Crashed when he did an update a few days ago and now he too could not install Adobe Reader... He kept getting the same error that I had gotten. After several attempts of uninstalling and reinstalling failures, I noticed a "More Details" button on the error message which was ( Error 1327.Invalid Drive: [drive letter].) It took me to a page on Adobe support with 2 possible fixes, I choose Option #2, which was to run the Microsoft Fixit program. After I followed the link and ran Microsoft Fixit, I was able to install Adobe Reader without any problems.
Being an Optomist, I thought maybe this fix did something that would fix my Premier Elements... prior to uninstalling and reinstalling, I thought I would just try to Lauch Premier Elements just on the wild chance that it would work and Surprise, Surprise, Surprise... it works just fine now. All my Adobe Products are working Great... go figure...
The Link to the fix is below:
Thanks for the follow up with the very great news "I found a SOLUTION!!".
The information that you shared may be the answer to a similar problem experienced by others. As I always write "Problems with the same symptoms can (often do) have different causes." But hopefully what worked for you will be the answers for others.
Great stick-to-it-tiveness and troubleshooting.
