This contains a version of SEGuide.exe that is functionally the same as the 4.1 distribution with hotfix 41EG16 (version 4.1.0.1020), but has an updated expiration date (01DEC2020). This SEGuide.exe should be applied ONLY TO SAS Enterprise Guide 4.1 installations that have hotfix 41EG16 applied. That is, this file can replace only the 4.1.0.1020 version of SEGuide.exe. If you apply it to another version of SAS Enterprise Guide (that has other hotfixes or no hotfixes), this EXE will cause the application to become unstable, due to the mixed-and-matched nature of the baseline of application files. To replace: - copy the enclosed SEGuide.exe to your SAS Enterprise Guide 4.1 folder, usually something like: C:\Program Files\SAS\Enterprise Guide 4 The SAS Enterprise Guide 4.1 hotfix page: http://ftp.sas.com/techsup/download/hotfix/ent_guide41.html
