I entered some invalid information into SQLyog and can not seem to get SQLyog to forget it. I tried uninstalling SQLyog but that did not work. When I reinstalled SQLyog the bad information was still there.

Where are you storing information that the uninstall does not remove?

Hi Dave,'
This is SQLyog issue. So, please post in the right category. I am moving this issue to 'SQLyog Bugs and Feature' section.

Hello,

Could you please answer questions given below?

Which version of SQLyog you installed, uninstalled and trying to install again?

What invalid information you entered in to SQLyog? You mean the Connection details? If so you have to do the steps given below. If not please explain how to reproduce it?

SQLyog got an sqlyog.ini file used to keep the connection details you saved, preference settings, and dialog persistances. Since SQLyog version 6.06 the .ini file stored in Appdata folder.
This .ini file never delete when you uninstall the SQLyog . So please go where your .ini file is and just rename it or delete it, and start SQLyog again.

You can find sqlyog.ini file in

for XP C:\Documents and Settings\{user}\Application Data\SQLyog

for Vista : C:\Users\{user}\AppData\Roaming\SQLyog
