Hello, trying to configure application deployment using SetupBuilder development edition. I can successfully install application using local IIS folder (http://computer_name:80/dep). Application correctly downloads all required files and installs. When trying to update using wupdate.exe, Network Communication Error : 5060 occurs. I know that is common error, but I read all related information from this forum and still cannot find a workaround:
1) IIS MIME-type settings for this folder allow "." extensions (treat as octet-stream) and I checked "IIS Server Image" checkbox, so install files are without extension. I also use "manifest" (without file extension) for manifest file.
2) I can successfully install application from this folder remotely, just cannot update.
3) I can download manifest file using Internet Explorer.
4) I tried to switch off firewall (both third-party and windows native). I also ensured, that wupdate.exe is allowed in firewall settings.
5) I checked registry settings after install and it seems its correct.

What else can I check to solve this problem?
