internet explorer - Script only works on some computers - The object invoked has disconnected from its clients -

i have following, simple jscript, checks time , whether or not current user in in specific skype response group.

if earlier 9:30, want user added response group (this done checking checkbox). after 9:30 , don't want them in group anymore.

togglesupport();  function togglesupport() {     var ie         = wsh.createobject('internetexplorer.application'),         url        = "https://lyncserver/rgsclients/tab.aspx",         id         = 'ctl05_ctl00_ctl04_ctl00_ctl00_ctl01';         date       = new date(),         hours      = date.gethours(),         minutes    = date.getminutes(),         time       = (hours * 60) + minutes,         ninethirty = 569; // 9:29 - because task runs @ 9:30       ie.visible = false;     ie.navigate(url);     while (ie.readystate != 4) wsh.sleep(25);      var element = ie.document.getelementbyid(id);     var insupport = element.checked;      if (time >= ninethirty) {         if (insupport) {             element.click();             var message = "removed support group (later thn 9:30)"         } else {message = "out of support after 9:30 - nothing change"}     } else if (time < ninethirty) {         if (!insupport) {             element.click();             var message = "added support group (earlier 9:30)"         } else {message = "in support before 9:30 - nothing change"}     }      wscript.echo(message);      wsh.sleep(1000);     ie.quit(); } 

this works on machine without issues whatsoever, when try executing on colleague's machine, error occurs:

line: 31

char: 2

error: object invoked has disconnected clients.

code: 80010108

source: (null)

i able narrow down location of error line:

while (ie.readystate != 4) wsh.sleep(25); 

so tried running script on affected computer try/catch in place:

try{     while (ie.readystate != 4) wsh.sleep(25); } catch (err){     wscript.echo("error when waiting page: " + err.name + " " + err.message);     return; } 

but see in wscript.echo is:

error when waiting page: error

where error returned err.name. unhelpful , doesn't tell me issue @ all.

i checked answers here, none of them seemed @ all, , don't explain why getting error.

we both using internet expliorer 11.0.9600.18524, , have same security settings.

is able shed light on why may happening?
