Howto: run several instances of proxy checker

This trick is about running several instances of proxy checker from different locations (folders).

To run 2 instances of Web Proxy Checker you need to create 2 folders for each instance (for ex. C:\WPC1 and C:\WPC2) and copy to these folders 4 files from C:\Program Files\Opt-In Software (I assume that proxy checker was installed to this folder):

wpcp.exe

WPCHost.exe

libeay32.dll

ssleay32.dll

Now you can run 2 instances of proxy checker (wpcp.exe) - first instance from folder C:\WPC1, second instance from folder C:\WPC2.

The problem here is that by default Web Proxy Checker stores application settings to user's Application Data folder. That means that all instances of program will share their settings. To avoid this problem you can use command line argument -appsettingsdir to specify where to save application settings.

To run first instance use this command:

C:\WPC1\wpcp.exe -appsettingsdir

To run second instance use this command:

C:\WPC2\wpcp.exe -appsettingsdir

The same trick works for other Opt-In Software applications: Web Searcher, Web URL Shortener, etc.
