Upload rights problem

Webix JS
1

We are evaluating webix upload, with perl.
On our test machine (2012R2), we have a problem at end of transfert, the return message is

{ status: 'server'
[Web Mar 18 15:08:03 2015] upload.pl: unlink0: 
C:\\Windows\\TEMP\\BU.... is gone already at C:\\inetpub\\wwwroot\\webstock\\upload.pl line 0.  }

It’s because IUSR doesn’t have write rights on C:\Windows\TEMP. We could add these rights but we prefer have an alternative solution to use an other temp directory…

Is there a solution for this?

It depends on used web-server

Client side only submit file to server side, the place where it stored is not enforced in any way.
