Service Packs

All service packs can only be used for updating the corresponding program version, i.e. a service pack for version 4.20 requires an existing installation of VISSIM 4.20. The dongle number entered on the previous page (e.g. 28887) has to correspond to the prefix of your hardlock key. (The subsequent sub-code .0 and the five-digit or six-digit customer number don't matter for service packs.) The updates are cumulative, meaning that the latest service pack includes all previous ones of the same main version.

Customers with a maintenance contract receive an update of each new main version automatically. Service packs are not mailed automatically, however. (Customers without a maintenance contract are kindly requested to send their enquiries to traffic.customerservice@ptv.de)

For the installation of the service pack, the downloaded zip file has to be unpacked with a suitable program. All files from the archive except vissim0.exe must be copied into the subdirectory Exe\ of your VISSIM installation. (Previously stored files with the same name should be renamed or moved to a different directory before this.)

vissim0.exe is the demo version which needs to be copied into the subdirectory CD\ExePlus\ together with all other files except VISSIM.exe if a demo version is to be delivered to a customer (see \Demo\CD\readme.txt on the VISSIM installation CD). If an installed demo version is to be updated, all files from the service pack except vissim.exe need to be copied into the Exe\ directory of the demo installation.
