MSICompressionType
TheMSICompressionTypeparameterdetermineswhethertocompressMSIfilesforpackagedistribution.
CompressionimprovesperformancewhenopeningMSIfilesandusingtheThinAppSDK.
IfyoucreateanMSIfileduringthecaptureprocess,ThinAppaddstheMSICompressionTypeparameterto
thePackage.inifileandsetstheinitialvalueofFastto
compressthefile.Decompressionoccursatthetime
ofinstallation.
YoudonothavetosettheMSICompressionTypeparametertoFastwhenyousettheCompressionType
parametertoFast.Settingbothparametersdoesnotincreasetheamountofcompression.
