Sample Isolation Mode Configuration Depending on Deployment
Context
Isolationmodescontrolthereadandwriteaccessforspecificsystemdirectoriesandsystemregistrysubkeys.
YoucanadjustisolationmodestoresolvetheproblemsinTable 3‐3.
View of Isolation Mode Effect on the Windows Registry
Figure 3‐3showsasectionoftheWindowsregistryforacomputerthathasolderMicrosoftOfficeapplications
installed.MicrosoftOffice2003createstheHKEY_LOCAL_MACHINE\Software\Microsoft\Office\11.0
registrysubtree.

WhenThinApprunsacapturedversionofMicrosoftVisio2007,ThinAppsetsthe

Problem Solution
Anapplicationfailstorunbecause
previousorfutureversionsexist
simultaneouslyorfailtouninstall
properly.
UsetheFullisolationmode.
ThinApphideshostcomputerfilesandregistrykeysfromtheapplication
whenthehostcomputerfilesarelocatedinthesamedirectoriesand
subkeysthattheapplicationinstallercreates.
For
directoriesandsubkeysthathaveFullisolation,theapplicationsonly
detectvirtualfilesandsubkeys.Anysystemvaluesthatexistinthesame
locationareinvisibletotheapplication.
Anapplicationfailsbecauseusersdidnot

environment.Theapplicationfailsto
modifyfilesand

UsetheWriteCopyisolationmode.
ThinAppmakescopiesofregistrykeysandfilesthattheapplicationwrites
