Normally, you would need to contact HP for Technical Support. As a courtesy, we are addressing your issue. PC-Doctor cannot be held responsible for any damage caused to your computer for providing you with the following information. Please follow these steps only if you accept responsibility for any damages that may result. As a reminder, please back up any important information.
An installation of Quicktime or Itunes may cause PC-Doctor to become unable to load due to a broken classpath. To find and edit the CLASSPATH variable, follow these steps:
1) Open the Control Panel. This can be found in the Start Menu. Double click on the System icon; this should open the "System Properties" dialog.
2) Select the Advanced tab; at the very bottom of the tab will be an "Environment Variables" button.
3) Click on the "Environment Variables" button to open the "Environment Variables" dialog.
4) Look for the CLASSPATH variable in the "System Variables" frame. Select the CLASSPATH variable and click on the Edit button; an "Edit System Variable" window will open.
5) Edit the variable value by adding a semicolon at the end of the line. The value should be something like this before you edit it: C:\Program Files\Java\j2re1.4.2\lib\ext\QTJava.zip. It will look like this after you edit it: C:\Program Files\Java\j2re1.4.2\lib\ext\QTJava.zip;
6) Select "OK" in the "Edit System Variable" dialog.
7) Select "OK" in the "Environment Variables" dialog.
8 ) Select "OK" in the "System Properties" dialog.
9) Now attempt to run your PC-Doctor product again.
If this is not successful, then please try reinstalling PC-Doctor. If PC-Doctor was pre-installed on your computer, the manufacturer probably provided you with recovery CDs, a mechanism to create recovery CDs, or a recovery program on the computer. Follow the instructions that came with your computer to reinstall PC-Doctor. If you have the original PC-Doctor installation files, simply run the Setup program. The latest code may also be downloaded from your OEMs website.
NOTE: To ensure your computer includes the program, perform steps 3 through 5 of the following procedure. If the Recovery Manager program is listed in the PC Help & Tools folder, your computer includes the program.
NOTE: Do not use the Recovery Manager program to reinstall software programs that came on CDs or DVDs included in the computer box. Reinstall these programs directly from the CDs or DVDs.
NOTE: Do not skip this last step. You must restart the computer when you are finished recovering software programs or hardware drivers.
