Mike,
1) I would recommend using MyEclipse 9, MyEclipse 7.5 is over 2 years old at this point. MyEclipse 9 also installers which can run silently based on input from a text file. Using this you can install MyEclipse correctly on all machines.
2) If you must stick with MyEclipse 7.5, when installing, you will be asked for two folders, please change these folders to generic locations that will work when replicated.
You will, however, need to create a .pulse2.locator file in the home directory of each user to point to the folder used – see the .pulse2.locator file created for your installation for an example.
3) How are you installing MyEclipse right now – using Pulse or using our offline installers? You could also use our archived update site or a special manual install (which you just have to unzip) for 7.5. If you wish to use any of these options, please write to support@genuitec.com with a link to this thread. Also include your subscription key and code.
