DI install is stuck at phase "unpack SAP archive"

Question

I try to install a DI on an MSCS cluster/SQL.
On the phase called "unpack SAP archive",  anyway SAPinst cannot move forward.
The sapinst_dev.log reads: (many repeated  loops as follows)
TRACE      [iaxxejsexp.cpp:199]
           EJS_Installer::writeTraceToLogBook()
2009-03-31 18:37:33.681 NWInstall._getFiles()

The sapinst.log reads:
WARNING 2009-03-31 14:52:04
Unable to get information about file
NT001C5555EP1\sapmnt\EP1\SYS\exe\uc\NTAMD64 using FindFirstFile. Operating system error message: You were not connected because a duplicate name exists on the network. Go to System in Control Panel to change the computer name and try again.
However explorer can access
NT001C5555EP1\sapmnt\EP1\SYS\exe\uc\NTAMD64  without any issue.
We can ping NT001C5555EP1 without errors.
DNS shows only one entry for above NT001C5555EP1.
How to fix it? Modify control.xml to allow the unpack anyway?
Points will be given. Thanks a lot!

Dear Friends:
I find out in the sapinst_dev.log:
TRACE      [iaxxejsexp.cpp:199]
           EJS_Installer::writeTraceToLogBook()
2009-04-01 15:03:41.212 NWInstall._needUnpacking() done:

2009-04-01 15:03:41.227 NWInstall._needUnpacking({
  cd:UKERNEL
  codepage:Unicode
  destination:
NT001C5555EP1\sapmnt\EP1\SYS\exe\uc\NTAMD64
  list:
  needUnpacking:true
  ownPath:
  path:DBINDEP\SAPEXE.SAR
  sid:QP1
  unpack:false
  wasUnpacked:false
In the control.xml, could you tell how to edit the follwoing so that the unpack can
take place? Now I am stuck at "unpack SAP archives":
NWInstall.prototype._needUnpacking = function(archive) {
  NW.trace("NWInstall._needUnpacking(", dump_properties(archive), ")");
  if (!archive.cd) {
    NW.trace("NWInstall._needUnpacking() done: optional archive, return false.");
    return false;
  var dest = FSPath.get(archive.destination);
  if (!dest.isExisting()) {
    if (installer.onUnix()) {
      // Handle the case where /usr/sap/SID/SYS/exe does not yet exist, but
      // /sapmnt/SID/exe is there. /usr/sap/SID/SYS/exe/run is a softlink to /sapmnt/SID/exe,
      // but /usr/sap/SID/SYS/exe/uc/platform should be /sapmnt/SID/exe/uc/platform.
      var destString = dest.toString();
      var sysExe = "/usr/sap/" + this.getSID() + "/SYS/exe";
      if (destString.indexOf(sysExe) == 0) {
        destString = this.getSAPMountDir() + "/" + this.getSID() + "/exe" + destString.substr(sysExe.length);
        destString = destString.replace(/\/run$/, "");
        NW.trace("NWInstall._needUnpacking() done: destination ", dest, " does not exist, testing ", destString);
        dest = FSPath.get(destString);
        if (!dest.isExisting()) {
          NW.trace("NWInstall._needUnpacking() done: destination ", dest, " does not exist, returning true.");
          return true;
      } else {
        NW.trace("NWInstall._needUnpacking() done: destination ", dest, " does not exist, returning true.");
        return true;
    } else {
      NW.trace("NWInstall._needUnpacking() done: destination ", dest, " does not exist, returning true.");
      return true;
  var files = NWInstall._getFiles(archive);
  for (var i = 0; i < files.length; ++i) {
    var f = dest.concat(files<i>);
    if (! f.isExisting()) {
      NW.trace("NWInstall._needUnpacking() done: ", f, " is missing, returning true.");
      return true;
  NW.trace("NWInstall._needUnpacking() done: false");
  return false;
Thanks!!
