jvermeer,
Can you try a clean install of 8.6 ?
Here are the steps :
1. Run the uninstaller.
2. Make sure the MyEclipse Install Directory has been completely removed
2.1. Pulse Install Directory, on XP it’s under C:\Program Files in \Pulse or \Genuitec, and on Vista it’s under <USER.HOME>\AppData\Local and then under \Pulse or \Genuitec again
3. Then make sure the pulse2.locator file under <USER.HOME> is erased as well
Install MyEclipse using either of the below mentioned options –
1. Download and install all-in-one installer from MyEclipse download site here – http://myeclipseide.com/module-htmlpages-display-pid-4.html
2. Install using pulse, instructions mentioned here – https://www.genuitec.com/forums/topic/installation-how-to-install-myeclipse-from-pulse/&highlight=
3. Install using archived update site – https://www.genuitec.com/forums/topic/installation-install-myeclipse-using-archived-update-site/&highlight=
Please note that the FAQs are not based on ME 8.6, please use 8.6 wherever applicable.
