1. "When starting Dupe Eliminator for iTunes I get the error 'JVM could not be started'. What is this?" - Dupe Eliminator for iTunes uses Java and when the application starts memory is reserved for the program. The default program settings allow for a maximum memory size of 1GB to be available to the program. If you are on a system where 1GB is not available you will get this error.

To fix it you need to override Dupe Eliminator for iTunes built-in defaults for memory usage. To do this you need to add one parameter when running the application.

• Right-click on the Dupe Eliminator for iTunes desktop icon and click on properties.
  
• Go to Target and add -J-Xmx512M to the end of the target. Make sure you add after the double quoted application exe path and name:
  

e.g."c:\Program Files\DupeEliminator\DupeEliminator.exe" -J-Xmx512M

This tells the program to use at the most 512MB (512 megabytes) -- adjust as needed.

2. "When starting Dupe Eliminator for iTunes I get a blank screen and nothing happens. I also see this error in my most recent log file (.e.g. c:\Program Files\DupeEliminator\logs\7-12-2008_Results.log): 'iTunes version is UNKNOWN! iTunes error - check your iTunes installation!' What is this?" - This problem is caused by a corrupted iTunes installation. The iTunes installation creates some Windows settings that are used by other applications such as Dupe Eliminator. These settings can sometimes become corrupted by other iTunes applications or rarely by iTunes itself.

Repair iTunes
To fix this problem you will need to run a repair on iTunes. Don't worry this does not mess with your iTunes Music Library, it just makes sure iTunes has all the correct files and double-checks iTunes Windows settings.

For XP, follow these steps:

1. Click the "Start menu" in the lower left of your screen
2. Click "Control Panel"
3. Click "Add or Remove Programs"
4. Scroll down until you see "iTunes" then click it.
5. Now click "Change" then click "Repair" and just let iTunes repair itself

For Vista, follow these steps:

1. Click the "Start menu" in the lower left of your screen
2. Click "Control Panel"
3. Click "Programs and Features"
4. Scroll down until you see "iTunes" then right-click it.
5. Now click "Repair" and just let iTunes repair itself

3. "I have a very large library, > 40,000 tracks, and Dupe Eliminator for iTunes doesn't finish processing/hangs" - this could be a running low on memory issue. Follow #1 above but increase the memory setting as follows:

• e.g. "c:\Program Files\DupeEliminator\DupeEliminator.exe" -J-Xmx1300M
• e.g. "c:\Program Files\DupeEliminator\DupeEliminator.exe" -J-Xmx1400M
• etc... until Dupe Eliminator can not start. Note the highest setting that works and use this setting.
• If you were able to use a setting of '-J-Xmx1300M' or higher, Dupe Eliminator for iTunes should run better...
  

4. "When activating the product, I get an the error message 'Your activation key is incorrect. Please reenter...'" .

1. Make sure you have entered no leading and trailing blanks for the activation key (also called activation ID).
   
2. Also make sure you are entering the activation key correctly or if you are pasting it from the clipboard that you copied the full activation key to the clipboard.
   
3. Copying the activation key you receive when you buy the product to the clipboard is the easiest way to enter your activation key.
4. For information on the Windows clipboard and copy and paste: introduction and examples.
   
5. If you still have problems, send an email requesting the lost or invalid activation key.
