Forexample,addRequiredLinks=\AppFolder\AppC\AppC.exetothefile.

IfyoustartApplicationA,itcanaccessthefilesandregistrykeysofApplicationBandApplicationBcan

Affecting Isolation Modes with Application Link
ThinApploadsanApplicationLinklayerduringapplicationstartupandmergesregistryentriesandfile
systemdirectories.IfThinAppfindsaregistrysubkeyorfilesystemdirectorythatdidnotpreviouslyexistin
themainpackageorlayerthatisalreadymerged,ThinAppusestheisolationmodespecifiedinthelayer
being
loaded.If theregistrysubkeyorfilesystemdirectoryexistsinthemainpackageandalayerthatisalready
merged,ThinAppusesthemostrestrictiveisolationmodespecifiedinanyofthelayersormainpackage.
The orderofmostrestrictivetoleastrestrictiveisolationmodesisFull,WriteCopy,and
Merged.
PermittedGroups Effect on Linked Packages
IfyoulinktwoapplicationsandyouspecifyavalueforthePermittedGroupsparameter,theuseraccount
usedforstartingtheapplicationmustbeamemberofatleastoneoftheActiveDirectorygroupsforthis
parameterinthePackage.inifilesofbothapplications.ForinformationaboutthePermittedGroups
parameter,
see“ConfiguringPermissions”onpage 72.
Sandbox Changes for Standalone and Linked Packages
Sandboxchangesfromlinkedpackagesarenotvisibletothebaseexecutablefile.Forexample,youcaninstall
AcrobatReaderasastandalonevirtualpackageandasalinkedpackagetothebaseFirefoxapplication.When
youstartAcrobatReaderasastandaloneapplicationbyrunningthevirtualpackageandyou
changethe
preferences,ThinAppstoresthechangesinthesandboxforAcrobatReader.WhenyoustartFirefox,Firefox
cannotdetectthosechangesbecauseFirefoxhasitsownsandbox.Openinga.pdffilewithFirefoxdoesnot
reflectthepreferencechangesthatexistinthestandaloneAcrobatReaderapplication.
Import Order for Linked Packages
ThinAppimportslinkedapplicationsaccordingtotheorderofapplicationsintheRequiredAppLinksor
OptionalAppLinksparameter.Ifeitherparameterspecifiesawildcardcharacterthattriggerstheimportof
morethanonefile,alphabeticalorderdetermineswhichpackageisimportedfirst.
TheOptionalAppLinksparametermightappearasOptionalAppLinks=a.exe;b.exe;plugins\*.exe.
Usinga.exeandb.exe
assampleexecutablefiles,ThinAppimportslinkedpackagesintheorderdescribed
inTable 4‐1.
Forinformationaboutnestedlinks,see“SetUpNestedLinkswithApplicationLink”onpage 58.
