SAP Router 721 更新后出现"找不到系统程序"错误.

SAPRouter的证书过期了. 因为SAP官方在2015.07月更新了SAPRouter的机制，所有客户的证书都作废了，所以SAPRouter也用不了。借这个机会，我把SAPRouter升级到了最新版本721. 

更新完成后，执行SAPRouter 721版本，发生错误：”找不到系统程序“.  后与SAP Support沟通后得知这问题在Notes 684106中有解决方案.

1. Go to thefollowing Internet address:
http://www.microsoft.com/technet/security/bulletin/MS09-035.mspx

2. On theleft-hand side, scroll to the "Affected Software" section.

3. Click the link:
Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package (KB973544)

4. Scroll to the"Files in This Download" section.

5. Download one ofthe following platform-specific files:

• Itanium system: vcredist_IA64.exe

• 64-bit SAP system on Intel 64-bit: vcredist_x64.exe

• 32-bit SAP system on Intel 64-bit: vcredist_x86.exe

• SAP system on Intel 32-bit: vcredist_x86.exe

6. Execute thedownloaded file and follow the installation instructions.

打上上述Package，就可以执行721版本的SAPRouter了.

建议大家都更新SAPRouter至最新版本721，可以解决很多问题. 之前640的SAPRouter版本只能使用R/3 connection，类似SSH, Telnet, WTS等连接即使开放了SAP也连不进来.更新到721后，这些连接都能顺利让SAP连进来了.

SAPRouter主机环境：Win 2003 X64.
