安装postgresql碰到Unable to write inside TEMP environment path

搞了半天，原来是 AVAST搞的鬼，把原来注册表的键值改成它自己了。其实应该是 C:WindowsSystem32vbscript.dll

The answer in the following page helpped me. http://forums.enterprisedb.com/posts/list/3040.page

1. run-> regedit and take backup of registry using export
2. HKEY_LOCAL_MACHINE->SOFTWARE->Classes->CLSID->B54F3741-5B07-11cf-A4B0-00AA004A55E8} -> InprocServer32
3. Modify registry entry with new value as C:WindowsSystem32vbscript.dll

In fact, I found there are 3 entries of HKEY_LOCAL_MACHINE->SOFTWARE->Classes->CLSID->B54F3741-5B07-11cf-A4B0-00AA004A55E8}, and set the first one as above, it works.
