The following client installer command line parameters are ignored when used in conjunction with KEEPCURRENTSETTINGS=1

 

·         SWICACHESIZE

·         MINFREESPACEMB

·         ALLOWINDEPENDENTFILESTREAMING

·          APPLICATIONSOURCEROOT

·         ICONSOURCEROOT

·         OSDSOURCEROOT

·         SYSTEMEVENTLOGLEVEL

·         SWIGLOBALDATA

·         DOTIMEOUTMINUTES

·         SWIFSDRIVE

·         AUTOLOADTARGET

·         AUTOLOADTRIGGERS

·         SWIUSERDATA

·         REQUIRESECURECONNECTION

To workaround this issue, a different mechanism needs to be used to configure the client with these settings. The App-V ADM Template can be used to set the following client settings from the list above: 

 

·         APPLICATIONSOURCEROOT

·         ICONSOURCEROOT

·          OSDSOURCEROOT

·         AUTOLOADTARGET

·         AUTOLOADTRIGGERS

·         DOTIMEOUTMINUTES

·         ALLOWINDEPENDENTFILESTREAMING

If KEEPCURRENTSETTINGS is not specified on the command line, install will behave as normal.  Any existing registry values will be overwritten by the installer.

 

Example command lines:

               

                setup.exe /s /v"/qn INSTALLDIR=C:\AppV /l*v setup.txt"

                msiexec.exe /i setup.msi /qn INSTALLDIR=C:\AppV /l*v setup.txt

 

Note INSTALLDIR is not one of the ADM values, so it can be specified on the command line regardless of whether KEEPCURRENTSETTINGS is specified.

 

If KEEPCURRENTSETTINGS is set to any value on the command line, install will not overwrite any existing registry values.

 

Examples:

 

There are no existing registry values.  This will behave a like normal install.

                setup.exe /s /v"/qn KEEPCURRENTSETTINGS=1 /l*v setup.txt"

               

ASR is set in the registry.  The following will not overwrite the existing value of ASR in the registry.

                setup.exe /s /v"/qn KEEPCURRENTSETTINGS=1 /l*v setup.txt APPLICATIONSOURCEROOT=c:\\my_asr"

               

                setup.exe /s /v"/qn KEEPCURRENTSETTINGS=0 /l*v setup.txt APPLICATIONSOURCEROOT=c:\\my_asr"

               

                setup.exe /s /v"/qn KEEPCURRENTSETTINGS="Yes" /l*v setup.txt APPLICATIONSOURCEROOT=c:\\my_asr"
