Quote - during all that I wonder how to access to Vista Ultimate 64 reg edit .

To delete completely your version of Vue in Vista:

(If you're just reinstalling, then you can skip step 5).

1. Uninstall (when available) from the Vista programs and features section. 

2. Delete the "C:Program Filese-on softwareVue 7 Infinite" folder. 

3. Delete the "C:Users(username)AppDataRoaminge-on software" folder. 

4. Delete the "C:Users(username)Documentse-on softwareVue 7 Infinite" folder. 

5. In the registry, delete the following keys: 
       HKEY_CURRENT_USERSoftwaree-on softwareVue 7 Infinite 
       HKEY_LOCAL_MACHINESOFTWAREe-on software 

6. If these .REG files are present, they should be removed: 
       "C:Windowse-on License Server 3.reg" 
       "C:WindowsVue 7 Infinite.reg" 

Additional information: 
The user folder is indeed in "C:Users(username)" on Vista. 
but it's in "C:Documents and Settings(username)" on XP/Win2K. 

For 64bit OS, here are the different application folders depending on your application: 
Vue 7 Infinite is located in "C:Program Filese-on softwareVue 7 Infinite" 
Vue 7 xStream 64bit is located in "C:Program Filese-on softwareVue 7 xStream" 
Vue 7 xStream 32bit is located in "C:Program Files (x86)e-on softwareVue 7 xStream" 

On MacOSX, the application folder is in: 
/Applications/Vue 7 Infinite 
or 
/Applications/Vue 7 xStream 

Still on MacOSX, the user folder is in: 
/Users/(username)/.e-on software/ 

Also, don't forget the temp folder: 

C:Users[your name]AppDataLocalTempeon 

Typically there can be lots of files there, too.
