applescript stopped working, error -1708

Here is another sample of the error.

This is from a a script to create a slug in InDesign.

tell application "Adobe InDesign CS6"

get font "Arial Narrow"

--> font "Arial Narrow"

set properties of text defaults of active document to {applied font:font "Arial Narrow", font style:"regular", capitalization:normal, justification:left}

activate

get active document

--> document id 1

count every page of active document

--> 1

get page 1 of active document

--> page id 208 of spread id 203 of document id 1

get layer "Slug" of document id 1

--> layer id 261 of document id 1

set active layer of active window to layer "Slug" of document id 1

get name of document id 1

--> "Untitled-1"

exists swatch "sluggreen" of document id 1

--> true

exists swatch "slugorange" of document id 1

--> true

get active page of active window

--> page id 208 of spread id 203 of document id 1

set slug bottom offset of document preferences of document id 1 to "40mm"

set slug top offset of document preferences of document id 1 to "10mm"

set slug inside or left offset of document preferences of document id 1 to "10mm"

set slug right or outside offset of document preferences of document id 1 to "10mm"

set horizontal measurement units of view preferences of document id 1 to millimeters

set vertical measurement units of view preferences of document id 1 to millimeters

get page width of document preferences of document id 1

--> 419.999999999167

get page height of document preferences of document id 1

--> 296.999999999461

round 419.999999999167

--> error number -1708

«event ascrgdut»

--> error number -1708

round 419.999999999167

--> error number -1708

Result:

error "Adobe InDesign CS6 got an error: 419.999999999167 doesn’t understand the round message." number -1708 from 419.999999999167

It is also not running any of the applescripts I use within FileMaker Pro.

Here is a sample of one I use to create folders on our server:

tell current application

do shell script "mkdir '/Volumes/Production_FP/test' 2> /dev/null"

Result:

error "\"mkdir '/Volumes/Production_FP/test' 2> /dev/null\" doesn’t understand the do shell script message." number -1708 from "mkdir '/Volumes/Production_FP/test' 2> /dev/null"

All these scripts did work a few days ago, and still work on other identical computers.

I have tried replacing the System/Library/ScriptingAdditions folder from the Time Machine backup, but this has not helped.

I have tried that, and got the following response:

tell current application

round 2.5

Result:

error "2.5 doesn’t understand the round message." number -1708 from 2.5

Could there be a problem with the StandardAdditions file?

I have replace the StandardAdditions file with a three-week old version from Time Machine and rebooted but no difference.

Great. Running that update on each of the affected machines has fixed the problem.

Many thanks.
